For every route builder, the first consideration is achieving a scenery consistent with the landscape they are mimicking.  Choice of objects, particularly vegetation (types of trees, for example.), is perhaps primary but topography&mdash;creating the terrain of hills, mountains, gullies, etc.&mdash;is of equal importance and should be the starting point for a new route or expansion of an existing route.  Another rule requiring consideration is the "decrease detail with distance" rule. The computer will attempt to render everything you have added within a scene, a scene that is constantly moving with the train being operated. Great detail may be called for close to the track, but not at distances far from the track; details should decrease with distance on the premise that no one is really going to notice them, no matter how much fun they might be to create, and rendering them places a cost on performance.

With respect to the layout of a Route or Map, Trainz users tend to follow one of two models: the '''Linear''' model or the '''Area''' model.  Placement of [[baseboard]]s end to end allows the Linear model to develop long track runs with minimal effort. An excellent example is "Belarusian woodland" by Oleg Khim.  The Area model (a large map of many baseboard squares) takes more effort but can better render distant scenery.  Excellent examples of this style are "Sebino Lake, Italy (1980s)" by jango and "Bodmin & Wenford Railway TRS2019" by marky7890. The two layouts styles are sometimes combined: area style layouts used for places of cities, dense industries, and complex train yards connected by long runs of linear style layouts. An example approaching this mixed style is "Coal Country" by Scratchy and "Rodnye Prostory - SND" by TrainzLagutin 1995.  Note that layout choice is independent of prototypical vs. imaginary route design. However, scenery choices will be influenced by the model you choose to employ.

With the Linear model, the edge of the baseboard is always a short distance away from the track, dictating specific scenery choices to obscure this fact from the view of the train. The Area model is especially suitable to creating  mountainous country, such as depicted in "TRS19 Canadian Rocky Mountains - Viktor Lake to Ross Peak & Glacier" by RoysTrainz. Mountains that rise high above the track elevation require space to gain that elevation without displaying unreal slopes  and "TRS2019 Canadian Rocky Mountains Ottertail to Castle Jct" by RoysTrainz shows just how big a map is needed to provide massive mountain peaks. The Area model can also be used to compress a lot of track in a small baseboard set by separating track areas with tall features (hills or backdrops). This layout "folds" a Linear track into an Area layout following techniques used by model railroad builders/designers.

===Edge of World ===
No matter the size of the layout developed, the reality is your world map will have an edge.  If a square or rectangular configuration of baseboards is maintained with expansion, this edge will simply appear as the end of the world so long as your viewpoint remains on the map. However, with the <b>Linear</b> style especially, maintaining a rectangular or square map is not possible for routes of any size. On flat terrain, the view from close to the tracks can show the sides of baseboards at the margins in what has been dubbed the "world edge effect". Fortunately, this problem can be reduced or avoided in a number of different ways. Here, we list the following aids to hide the "world edge":

The ever popular "Mojave Sub Division" by Jointedrail presents an interesting situation.  A prototypical route, track direction and terrain are set by the real world and terrain varies from steep, high hills  to flat desert and valley bottom, in places changing dramatically. The "world edge" effect is dealt with by the breadth of this linear layout (width varies from 6 to 12 baseboards), yet the "edge" remains conspicuous in many locations.  A relatively small Area style route depicting terrain with minimal topography that deftly handles hiding the map edges is "Fall Harvest-Nebraska" by Robert3a0.  In this route, minimizing the vertical faces of baseboards applies two tricks: distancing the tracks from the edges and using long straight arrangements of baseboards.

Enhancing topography changes a flat baseboard into one with hills and valleys, opening up opportunities for road and railroad cuts, viaducts and bridges, and, of course, tunnels.  Varied topography establishes glimpses of the wider world as a train moves down the track.  Of course, a generally flat terrain is realistic for many parts of the world and certainly not a 'bad' thing. Topography on a Route is developed using the <span class="plainlinks">'''[https://online.ts2009.com/mediaWiki/index.php/Help/Topology_Tab Topology tool]'''</span> in Surveyor mode (correct term would be "topography").  The top row in this tool menu has settings for <b><i>Height up 'U'</i></b>, <b><i>Height down 'D'</i></b> and <b><i>Adjust height 'A'</i></b>.  These settings determine what the topography tool will do when applied to the surface of the map and a selection must be made before the tool will work. However, before applying, set the radius and sensitivity of the tool with the <b><i>Cursor radius '+/-'</i></b> and <b><i>Sensitivity '[/]'</i></b> dials, respectively.  The next row has additional settings, the most useful of which is on the right: the <b><i>Plateau 'P'</i></b> setting.  The <b><i>Get height 'G'</i></b> setting appears to do nothing in Trainz2019. The <b><i>Use height 'H'</i></b> setting sets the topography tool to draw the ground at the height setting entered in the box to the left.

However, the elevation of a point on the baseboard can be obtained using the <b>Plateau 'P'</b> tool instead. The <b><i>Use height 'H'</i></b> window sets the topography tool to draw the ground at the elevation setting entered (or obtained with the Plateau 'P' tool) in the Height Value window to the left.

The process of creating a varied terrain starts by raising (and perhaps lowering) the ground surface using moderate radius and sensitivity settings (or higher settings to create mountainous topography). Practice using different settings for radius and sensitivity to develop skill in using these tools.  Once the basic terrain has been established, the <b><i>Plateau 'P'</i></b> tool can be an excellent smoothing instrument, even on sloped ground.  Set the sensitivity high and the radius on however large an area is to be smoothed (best results are achieved using a high radius setting).  The Plateau setting uses the elevation at the tool center; moving it quickly over a limited area and regularly resetting the center point will change a rough surface into a smooth slope. Moving the tool along a contour works best.  Again, practice  is necessary to acquire this skill.  Assuming your tracks are already in place, this setting (with radius set at small) allows you to bring slopes in close for realistic cuts or fills near the line.

All land is the result of the forces of erosion and gravity acting upon some earlier (geologically earlier) uplift. You can raise up the land, but fine tuning is then applied for a more realistic look and this entails removing portions of the uplift. Steeper slopes (cliffs) represent more resistant material: that is, rock; but mass-wasting (localized landslides) can create a cliff in more easily eroded material.  Indeed, concave slopes present a picture of substantial, on-going erosion whereas convex slopes are more often seen in late-stage eroded landscapes (hills and gentle valleys). However, these are generalizations and slope form is highly varied in most regions. The <b><i>Height up 'U'</i></b>, <b><i>Height down 'D'</i></b> and <b><i>Plateau 'P'</i></b> tools are used to shape the land, usually at small to medium radius and medium sensitivity settings.  Height up 'U' produces a convex surface and Height down 'D' produces a concave surface where applied on a slope.
 +
 
 +
Very fine adjustments around tracks, roads, or buildings require putting radius and sensitivity at their lowest settings and clicking as needed to adjust the land height in relation to the object. Two things need be understood in applying this action, foremost of which is the fact that only clicking directly on a grid vertex point will cause the ground to rise or fall.  If hidden by ground texture, you may need to move around a bit to find the "sweet spot".  Secondly, raising or lowering the ground may also raise or lower the object, requiring later object height adjustment.  However, for spline objects, if the height has been set (the white spinning circle changed to a yellow spinning circle) adjustment of the ground surface will not effect the spline vertex and raising the ground can bury part of the spline.

A new baseboard has a flat surface at 0.00 (feet or meters). Transforming this into a higher (or lower) elevation can be time-consuming using the height up or down tools available in the <b>Topology</b> Menu.  Putting the Radius 'R' at maximum will speed up the process, but the <b>Use height 'H'</b> tool can make fast work of bringing up the entire (or much of) the new baseboard to an elevation typed into the Height value window and then "painting" with the tool across the baseboard surface. To extend tall hills or mountains, the <b>Copy and paste</b> tool is an even faster option.  Copy a large area from a previously created upland, unselecting all but the <b>Paste height</b> option, then in <b>Paste mode</b> drop the copied area onto the new location(s).  Do not unselect the <b>Paste textures</b> mode if you also wish to maintain the colors/textures from the original version. Use the Plateau 'P' tool to smooth out transition areas.

Two types of assets exist in Trainz: <b>objects</b> and <b>splines</b>.  In surveyor mode, scenery objects are added and manipulated using the Objects Menu reached by clicking on the <b>Objects 'F3'</b> tab. Tracks and objects directly related to tracks are dealt with separately under the <b>Tracks 'F4'</b> tab. For explanations on the various tools and settings provided see pages describing the <span class="plainlinks">[https://online.ts2009.com/mediaWiki/index.php/Help/Objects_Tab Objects Tab]</span> and <span class="plainlinks">[https://online.ts2009.com/mediaWiki/index.php/Help:Surveyor_Track_Tools Tracks Tab]</span>.

===Spline Shadows===
Implementation of shadows cast by objects was one of the great steps forward made by Trainz to render a realistic GUI.  Certain objects, notably spline objects with a low profile (such as roads and tracks) should not, of course, cast a shadow. To avoid this problem, the spline must be set down tight against the ground; any gap between the spline and the ground will appear as a dark line (the shadow).  Spline objects conform to variations in slope as the spline is laid, but fixing the spline points (changes the point from a white to yellow rotating circle) with the <b>Adjust spline height 'H"</b> setting in <b>Tracks 'F4'</b> or <b>Spline height 'H' </b> in <b>'Spline mode 'S'</b> for <b>Objects 'F3'</b>) removes ground conforming between the points.  Small rises now bury the spline and small dips produce a shadow. On a perfectly level board, these problems do not occur.

On a perfectly level board, these particular problems do not occur, although many spline objects will still cast a shadow if not height adjust. The solution is to bring the spline segments back into close conformance with the ground. Two possible approaches &mdash;adjust the spline height or adjust the ground height&mdash;may both need to be utilized wherever on a Route the shadowing is clearly observable.
 +
 
 +
A first step is to use the <b>'Smooth spline 'S'</b> tool found in the <b>Advanced</b> section of the Spline Mode menu (same tool is <b>Smooth spline height 'S'</b> in the advanced tools for <b>Tracks 'F4'</b>). This tool corrects the terrain topography under the spline segment (section between two vertices) clicked on.  The spline is smoothed and the ground brought into conformance with the spline.  But this conformance may or may not eliminate a shadow, depending on the particular asset, as many are created to lie slightly above the ground. The next step is to apply the <b>'Spline height 'H'</b> tool under Advanced )<b>Adjust spline height 'H'</b> for track splines), lowering the vertices while holding down the CTRL key (allows very fine adjustments).  Using the Smooth spline height tool may not be desirable in some situations, as it has an impact over topography some distance from the spline (may level the ground too far out from the road or track). In this case, the ground will need to be raised up to the spline to eliminate the shadow. The tool used is <b>Height up 'U'</b> in the <b>Topology</b> menu, putting both Radius and Sensitivity on the absolute lowest settings. The <b>Height down 'D'</b> tool may need to be employed to make adjustments.  Realize, both tools only operate if clicked on a grid vertex, having no effect if clicked away from a vertex. The tools raise or lower a vertex and the ground "follows" as a surface determined by the surrounding vertices.
 +
 
 +
Achieving "no shadow" may be impossible in some small parts of a segment due to bending of the spline. Moving the spline point closer to a grid vertex may help. Using spline assets with "skirts" (for example, ballast in track splines) certainly makes the process easier as these have greater height latitude. Simply hiding conspicuous shadows with a grass asset or placing an object like a car on the shadow are other options.

===Grid Size Effect===
One reason to not over utilize the 5-m grid size on a layout is the little difference selecting 5-m over 10-m makes for all but limited areas on a Route. Consider just two tiles; say ballast laid along a track cutting through grass.  On a 10-m grid, the ballast tends to flare out in triangles (depending upon the track angle relative to the underlying grid) or not appearing under the track at all in other places.  In the figure at left, the interaction of dry grass tiles and ballast tiles along the track in the distance shows triangles of ballast at 10-m grid setting. On a 5-m grid, this effect is much reduced, similar to that seen along the track in the foreground of the figure.  The ballast is more easily constrained to the vicinity of the track and the line between grass and ballast can be made closer to an expected line parallel with the rails. In essence, a 5-m grid does permit more precision in painting the ground color/texture where multiple colors/textures are interacting. This precision appears to be the only real advantage gained at the expense of an enhanced cost to performance, suggesting careful consideration of which baseboards might really benefit from having a 5-m grid setting. In fairness, the adverse rendering of adjacent tile interaction on a 10-m grid is less noticeable at low angles and can be ameliorated somewhat by using tiles having less contrast.

The number of choices of coloring tiles is large, easily in the hundreds. Picking a suitable tile or combination of tiles is first a matter of deciding what sort of ground you wish to portray. The basic categories are going to be: vegetation, rock, bare soil, and water. Vegetation is likely to occupy the largest area of the map, except in very dry climates (e.g., deserts, dominated by bare soil) and rocky areas with thin soils. Water is discussed in more detail below under "Water Features".

Initially, decide on a suitable "theme" color best representative of the location and type of terrain you intend to emphasize (say, dry grassland) and paint broad areas with this theme color.  The purpose here is to unify your rout's overall look. Of course, you might have more than one theme color if patches are typical or hills look different than valleys or plains.

=== Tile basics ===
Coloring the map surface is done by spreading small tiles over the map grid. We call these "tiles" because each is a usually six-sided pattern that is repeated <i>ad infinitum</i> as it is laid down (painted). On the 10-m grid, the tool places a tile diagonally (NW to SE or NE to SW) only centered on the yellow grid intersections. You can control the area covered by the tool (<b>Radius "-/+"</b>) and the pattern size (<b>Texture scale "Ctrl [/]"</b>)&mdash;this is not the area covered, but an enlargement of the actual pattern. Available tiles range from plain color to complex patterns mimicking ground textures of all sorts. Many of these are very good and others, not so good. Because the painting involves laying tiles one after the other, <b>secondary patterns</b> are almost inevitable. The better texture tiles avoid this.  If a created tile is even a little darker in one part than elsewhere, a secondary pattern will appear. How troublesome these secondary patterns are depends upon the viewed distance. Viewed from the cab, chase, or lineside cameras, secondary patterning is not a huge problem.

Secondary patterns can be distracting but several options exist to minimize the problem. First, for broad (e.g., "theme") area painting, select tiles that lack strong contrasts in color (appear highly textured) as these produce very noticeable secondary patterns. Here, selection for color is more important than texture; save highly textured tiles for areas close to the track. Use the Texture scale 'Ctrl [/]' set high or at maximum to reduce the frequency of repeat of the pattern.  Regularly change the Texture direction '[/]' and Scale settings as the tile is painted over broad areas to break up the secondary pattern, although adjusting Texture scale Ctrl '[/]' too far downward may not be helpful. Another option might be to create a complex ground pattern mixing several different tiles and applying this to the broader areas using the Copy and paste tool. Finally, realize that covering the ground with a high density of objects (such as lots of trees) can effectively obscure the secondary pattern (of the forest floor).

Painting water establishes a level surface at the setting in the ''water surface height'' box. Expanding this surface always maintains the same height as long as you begin painting from the existing surface (no need to adjust the setting).  The  <b><i>Adjust height 'E'</i></b> tool adjust the entire connected surface all at once, but does not change any other water surfaces on the map not connected to the one being adjusted. Thus, you can create a series of lakes at different elevations so long as the water surfaces of each are not connected. Determine this independence by selecting <b>Wireframe View</b> in the <b>Display Menu</b> (or pressing <b>F9</b>). This displays the baseboard in white and the water surface(s) in grey, removing all the painted surfaces.  Use the <b><i>Remove water 'Q'</i></b> tool to disconnect close-by water surfaces that you wish to set to different heights. Working upstream of a long river, you can progressively raise the surface of segments at points with rapids, waterfalls, or dams. Just be sure the water surface is broken at these points. An oddity built into the <b><i>Adjust height </i></b> tool is that if you hold down the Shift-Key while raising or lowering the water surface, the surface becomes bendy, going up or down within a limited area, no longer representing a level surface. If you bend it too much, it snaps back to a level surface at some new height. There must be a use for this?

In a landscape of topographic relief (mountainous), extending a linear feature with the level water surface may prove impractical, requiring that the water surface be broken up into unconnected segments that can rise step-like as the stream extends upslope.  A good example of how to "connect" these segments is provided in the MPS Route, "Sgt_Fury4449's Epic route" where a wild river is depicted flowing from tributaries and lakes down to a coastal estuary.

Creeks and small streams can be perennial (contain water year-round) or intermittent (flowing water present during the wet season).  Dry streams might be created by a contrasting tile "material" representing sand, mud, or rounded boulders/gravel as a bed winding across the terrain beyond the banks.  A number of stream spline objects are available to represent water, the splines presenting different widths and colors (search the Download Station for "stream" and "river"). For wider splines, first create the physical channel, lay the spline in, and then cover the edges by raising the banks. Narrow splines can be used in short segments where the water is just glimpsed within a dense riparian vegetation. If you do not set the spline height, the depicted feature will follow the ground surface (bed) you created.

Latest revision as of 21:10, 27 September 2022

Trainz aficionados are a diverse group with varied interests in one or more of the multiple aspects of this game. Developing the scenery that surrounds the tracks is one such aspect, but one that only a few have really mastered. This How-To page will introduce those interested in improving the look of their route to techniques they can learn and apply. Although scenery objects (assets) are important and will be discussed, the focus here is on the landscape itself: the use of the Topology (sic) and Paint tools in Surveyor Mode. Although applicable to any version of Trainz, the text is based on the tools and renderings available in TRS2019.

Contents

[edit] Layout

The first thing to understand about layout of a Route is the ground type. From TS2009 onward, Trainz releases have included two ground types:

  • classic, 10-m grid - the original Trainz ground type and the default;
  • classic, 5-m grid - ground type using the classic texturing technique, but storing four times the number of sample points.

The 5-m grid is great for fine detail close to the track but, as always, with an increase in detail comes a potential impact on performance. A mix of 10- and 5-m grids can be utilized: the 5-m grid used near the track where high detail is desirable, the 10-m grid in all other places. Implementing grid type is discussed elsewhere (see Ground Types) but realize that the grid type is set independently for each baseboard and not some portion of a baseboard. Only the Paint and Topology tools are impacted by the grid size setting.

With respect to the layout of a Route or Map, Trainz users tend to follow one of two models: the Linear model or the Area model. Placement of baseboards end to end allows the Linear model to develop long track runs with minimal effort. An excellent example is "Belarusian woodland" by Oleg Khim. The Area model (a large map of many baseboard squares) takes more effort but can better render distant scenery. Excellent examples of this style are "Sebino Lake, Italy (1980s)" by jango and "Bodmin & Wenford Railway TRS2019" by marky7890. The two layouts styles are sometimes combined: area style layouts used for places of cities, dense industries, and complex train yards connected by long runs of linear style layouts. An example approaching this mixed style is "Coal Country" by Scratchy and "Rodnye Prostory - SND" by TrainzLagutin 1995. Note that layout choice is independent of prototypical vs. imaginary route design. However, scenery choices will be influenced by the model you choose to employ.

With the Linear model, the edge of the baseboard is always a short distance away from the track, dictating specific scenery choices to obscure this fact from the view of the train. The Area model is especially suitable to creating mountainous country, such as depicted in "TRS19 Canadian Rocky Mountains - Viktor Lake to Ross Peak & Glacier" by RoysTrainz. Mountains that rise high above the track elevation require space to gain that elevation without displaying unreal slopes and "TRS2019 Canadian Rocky Mountains Ottertail to Castle Jct" by RoysTrainz shows just how big a map is needed to provide massive mountain peaks. The Area model can also be used to compress a lot of track in a small baseboard set by separating track areas with tall features (hills or backdrops). This layout "folds" a Linear track into an Area layout following techniques used by model railroad builders/designers.

[edit] Edge of World

No matter the size of the layout developed, the reality is your world map will have an edge. If a square or rectangular configuration of baseboards is maintained with expansion, this edge will simply appear as the end of the world so long as your viewpoint remains on the map. However, with the Linear style especially, maintaining a rectangular or square map is not possible for routes of any size. On flat terrain, the view from close to the tracks can show the sides of baseboards at the margins in what has been dubbed the "world edge effect". Fortunately, this problem can be reduced or avoided in a number of different ways. Here, we list the following aids to hide the "world edge" (each is discussed below under the appropriate subject):

  • behind scenery objects;
  • behind backdrops or a "double rise" (distant high terrain);
  • behind higher elevation topography (hills or mountains);
  • by extending water (ocean or large lake) to the "horizon".

The ever popular "Mojave Sub Division" by Jointedrail presents an interesting situation. A prototypical route, track direction and terrain are set by the real world and terrain varies from steep, high hills to flat desert and valley bottom, in places changing dramatically. The "world edge" effect is dealt with by the breadth of this linear layout (width varies from 6 to 12 baseboards), yet the "edge" remains conspicuous in many locations. A relatively small Area style route depicting terrain with minimal topography that deftly handles hiding the map edges is "Fall Harvest-Nebraska" by Robert3a0. In this route, minimizing the vertical faces of baseboards applies two tricks: distancing the tracks from the edges and using long straight arrangements of baseboards.

[edit] Hills and Valleys

Enhancing topography changes a flat baseboard into one with hills and valleys, opening up opportunities for road and railroad cuts, viaducts and bridges, and, of course, tunnels. Varied topography establishes glimpses of the wider world as a train moves down the track. Of course, a generally flat terrain is realistic for many parts of the world and certainly not a 'bad' thing. Topography on a Route is developed using tools found in the Topology menu in Surveyor mode (correct term would be "topography"). The top row in this menu has tools for Height up 'U', Height down 'D' and Adjust height 'A'. These tools are explained on the Topology Help Page. However, before applying, set the radius and sensitivity of the tool with the Cursor radius '+/-' and Sensitivity '[/]' dials, respectively. The next row has additional settings, the most useful of which is on the right: the Plateau 'P' tool. The Get height 'G' tool appears to do nothing useful in TRS2019 (see "Problems" at bottom). However, the elevation of a point on the baseboard can be obtained using the Plateau 'P' tool instead. The Use height 'H' window sets the topography tool to draw the ground at the elevation setting entered (or obtained with the Plateau 'P' tool) in the Height Value window to the left.

The process of creating a varied terrain starts by raising (and perhaps lowering) the ground surface using moderate radius and sensitivity settings (or higher settings to create mountainous topography). Practice using different settings for radius and sensitivity to develop skill in using these tools. Once the basic terrain has been established, the Plateau 'P' tool can be an excellent smoothing instrument, even on sloped ground. Set the sensitivity high and the radius on however large an area is to be smoothed (best results are achieved using a high radius setting). The Plateau setting uses the elevation at the tool center; moving it quickly over a limited area and regularly resetting the center point will change a rough surface into a smooth slope. Moving the tool along a contour works best. Again, practice is necessary to acquire this skill. Assuming your tracks are already in place, this setting (with radius set at small) allows you to bring slopes in close for realistic cuts or fills near the line.

All land is the result of the forces of erosion and gravity acting upon some earlier (geologically earlier) uplift. You can raise up the land, but fine tuning is then applied for a more realistic look and this entails removing portions of the uplift. Steeper slopes (cliffs) represent more resistant material: that is, rock; but mass-wasting (localized landslides) can create a cliff in more easily eroded material. Indeed, concave slopes present a picture of substantial, on-going erosion whereas convex slopes are more often seen in late-stage eroded landscapes (hills and gentle valleys). However, these are generalizations and slope form is highly varied in most regions. The Height up 'U', Height down 'D' and Plateau 'P' tools are used to shape the land, usually at small to medium radius and medium sensitivity settings. Height up 'U' produces a convex surface and Height down 'D' produces a concave surface where applied on a slope.

Very fine adjustments around tracks, roads, or buildings require putting radius and sensitivity at their lowest settings and clicking as needed to adjust the land height in relation to the object. Two things need be understood in applying this action, foremost of which is the fact that only clicking directly on a grid vertex point will cause the ground to rise or fall. If hidden by ground texture, you may need to move around a bit to find the "sweet spot". Secondly, raising or lowering the ground may also raise or lower the object, requiring later object height adjustment. However, for spline objects, if the height has been set (the white spinning circle changed to a yellow spinning circle) adjustment of the ground surface will not effect the spline vertex and raising the ground can bury part of the spline.

PencilTips.PNGAdjusting the ground height around a spline vertex can be frustrating if you have not first "fixed" the vertex height.

[edit] Topography Shortcuts

A new baseboard has a flat surface at 0.00 (feet or meters). Transforming this into a higher (or lower) elevation can be time-consuming using the height up or down tools available in the Topology Menu. Putting the Radius 'R' at maximum will speed up the process, but the Use height 'H' tool can make fast work of bringing up the entire (or much of) the new baseboard to an elevation typed into the Height value window and then "painting" with the tool across the baseboard surface. To extend tall hills or mountains, the Copy and paste tool is an even faster option. Copy a large area from a previously created upland, unselecting all but the Paste height option, then in Paste mode drop the copied area onto the new location(s). Do not unselect the Paste textures mode if you also wish to maintain the colors/textures from the original version. Use the Plateau 'P' tool to smooth out transition areas.

[edit] Object and Spline Assets

Two types of assets exist in Trainz: objects and splines. In surveyor mode, scenery objects are added and manipulated using the Objects Menu reached by clicking on the Objects 'F3' tab. Tracks and objects directly related to tracks are dealt with separately under the Tracks 'F4' tab. For explanations on the various tools and settings provided see pages describing the Objects Tab and Tracks Tab.

[edit] Spline Shadows

Implementation of shadows cast by objects was one of the great steps forward made by Trainz to render a realistic GUI. Certain objects, notably spline objects with a low profile (such as roads and tracks) should not, of course, cast a shadow. To avoid this problem, the spline must be set down tight against the ground; any gap between the spline and the ground will appear as a dark line (a shadow). Spline objects conform to variations in slope as the spline is laid, but fixing the spline points (this changes the vertex from a white to a yellow rotating circle) with the Adjust spline height 'H" setting in Tracks 'F4' or Spline height 'H' in 'Spline mode 'S' for Objects 'F3') removes ground conforming between the points. Small rises now bury the spline and small dips produce a shadow. On a perfectly level board, these particular problems do not occur, although many spline objects will still cast a shadow if not height adjust. The solution is to bring the spline segments back into close conformance with the ground. Two possible approaches —adjust the spline height or adjust the ground height—may both need to be utilized wherever on a Route the shadowing is clearly observable.

A first step is to use the 'Smooth spline 'S' tool found in the Advanced section of the Spline Mode menu (same tool is Smooth spline height 'S' in the advanced tools for Tracks 'F4'). This tool corrects the terrain topography under the spline segment (section between two vertices) clicked on. The spline is smoothed and the ground brought into conformance with the spline. But this conformance may or may not eliminate a shadow, depending on the particular asset, as many are created to lie slightly above the ground. The next step is to apply the 'Spline height 'H' tool under Advanced )Adjust spline height 'H' for track splines), lowering the vertices while holding down the CTRL key (allows very fine adjustments). Using the Smooth spline height tool may not be desirable in some situations, as it has an impact over topography some distance from the spline (may level the ground too far out from the road or track). In this case, the ground will need to be raised up to the spline to eliminate the shadow. The tool used is Height up 'U' in the Topology menu, putting both Radius and Sensitivity on the absolute lowest settings. The Height down 'D' tool may need to be employed to make adjustments. Realize, both tools only operate if clicked on a grid vertex, having no effect if clicked away from a vertex. The tools raise or lower a vertex and the ground "follows" as a surface determined by the surrounding vertices.

Achieving "no shadow" may be impossible in some small parts of a segment due to bending of the spline. Moving the spline point closer to a grid vertex may help. Using spline assets with "skirts" (for example, ballast in track splines) certainly makes the process easier as these have greater height latitude. Simply hiding conspicuous shadows with a grass asset or placing an object like a car on the shadow are other options.

[edit] Backdrops

Backdrops are used to create the illusion of distant terrain, enabling builders to set up landscaped horizons such as mountains and cityscapes quicker and with less impact to the frame-rate. To achieve this, a backdrop has a much greater draw distance than other scenery assets so that it is visible from far away (5 km or ~5000 yds). Backdrops are valuable with layouts based on the Linear Model, particularly where there is minimal topography (steppes and plains), obviating the need to add map squares to create a sense of distance beyond the tracks. Even in Area Model layouts backdrops can be used to great advantage, as is aptly demonstrated by Jango in "Sebino Lake, Italy (1980s)" in which distant villages are skillfully rendered by short backdrops.

Backdrops are provided as either object assets or spline assets. Because these assets are relatively easy to create and typically designed for specific purposes to match the developer's route, backdrops available on the DLS vary widely in subject and quality. Search for "backdrop" in the DLS for access to an extensive number of offerings.

A form of backdrop labeled a "double rise" is created with the Topology tool. A low hill or objects (for example trees or buildings) are used close by the tracks to obscure the land immediately beyond, which is made to slope downward, then rise up to create the illusion of far distant mountains or hills. The illusion is accomplished by using no objects or small objects to represent very distant trees on the far rise. Painting and topography also contribute by using muted colors tending to more purple shades. An example of this approach can be seen in the MSP route "Sgt_Fury4449's Epic route", where a distant snow-capped range is actually much closer to the tracks than would be possible in a narrow layout. The dip between the tracks and the far rise is obscured from view taking away from the viewer cues normally present to assess distance.

[edit] Coloring (Painting)

Coloring the landscape ("ground texturing") is accomplished with the Surveyor Paint Tool OR Paint tool. This tool opens a display of all the of the "paints" or tiles residing locally on your computer. Each combines colors and textures (in 2D) providing hundreds of possible choices for painting the ground. This tool is a paint brush with the ability, after selecting a tile, of enlarging the tile image (Texture scale 'Ctrl [/]') and changing the tile orientation Texture direction '[/]'). The diameter of the brush tool is set by the Radius '-/+' dial. A Get texture 'G' tool turns on a pointer that, when clicked on a painted location on the map, loads the tile in the brush. The loaded tile is shown in the square directly above the "Radius" dial. If you locate a tile by typing a word/name in the box above the tile display columns, the square displaying the loaded tile does not work if you then select a tile using the selection tool, even though the selected tile is likely loaded into the brush. We say "likely" because a painted area can become a combination of several different tiles, with certain tiles dominating the selection tool to the exclusion of what is displayed.

Once a selected tile is loaded, the image can be painted across the terrain.

Open up the Edit Menu (top menu bar, second from left) and pick Edit Environment from the list. This opens up a small window titled Environment - Lighting. To the right of the cloud preview window and boxes to select ambient, sun, and water color is a vertical slider. Clicking on the green dot at the bottom of the time dial turns the slider on for midday. Now adjust the slider to set a proper brightness; too bright, and your color tile selections will look washed out.

Baseboard with grid-size of 10-m

[edit] Grid Size Effect

One reason to not over utilize the 5-m grid size on a layout is the little difference selecting 5-m over 10-m makes for all but limited areas on a Route. Consider just two tiles; say ballast laid along a track cutting through grass. On a 10-m grid, the ballast tends to flare out in triangles (depending upon the track angle relative to the underlying grid) or not appearing under the track at all in other places. In the figure at left, the interaction of dry grass tiles and ballast tiles along the track in the distance shows triangles of ballast at 10-m grid setting. On a 5-m grid, this effect is much reduced, similar to that seen along the track in the foreground of the figure. The ballast is more easily constrained to the vicinity of the track and the line between grass and ballast can be made closer to an expected line parallel with the rails. In essence, a 5-m grid does permit more precision in painting the ground color/texture where multiple colors/textures are interacting. This precision appears to be the only real advantage gained at the expense of an enhanced cost to performance, suggesting careful consideration of which baseboards might really benefit from having a 5-m grid setting. In fairness, the adverse rendering of adjacent tile interaction on a 10-m grid is less noticeable at low angles and can be ameliorated somewhat by using tiles having minimal contrast.

[edit] Picking tile colors

The number of choices of coloring tiles is large, easily in the hundreds. Picking a suitable tile or combination of tiles is first a matter of deciding what sort of ground you wish to portray. The basic categories are going to be: vegetation, rock, bare soil, and water. Vegetation is likely to occupy the largest area of the map, except in very dry climates (e.g., deserts, dominated by bare soil) and rocky areas with thin soils. Water is discussed in more detail below under "Water Features".

Initially, decide on a suitable "theme" color best representative of the location and type of terrain you intend to emphasize (say, dry grassland) and paint broad areas with this theme color. The purpose here is to unify your route's overall look. Of course, you might have more than one theme color if patches are typical or hills look different than valleys or plains. Understand that no single tile provides an entirely natural look if not augmented to some degree by other tiles. These contrasting colors/textures might represent bare patches in the vegetation or subtle shadings or local changes in vegetation or soil type reflective of the real world.

[edit] Tile basics

Coloring the map surface is done by spreading small tiles over the map grid. We call these "tiles" because each is a usually six-sided pattern that is repeated ad infinitum as it is laid down (painted). On the 10-m grid, the tool places a tile diagonally (NW to SE or NE to SW) only centered on the yellow grid intersections. You can control the area covered by the tool (Radius "-/+") and the pattern size (Texture scale "Ctrl [/]")—this is not the area covered, but an enlargement of the actual pattern. Available tiles range from plain color to complex patterns mimicking ground textures of all sorts. Many of these are very good and others, not so good. Because the painting involves laying tiles one after the other, secondary patterns are almost inevitable. The better texture tiles tend to minimize this. If a created tile is even a little darker in one part than elsewhere, a secondary pattern will appear. How troublesome these secondary patterns are depends upon the viewed distance. Viewed from the cab, close-in chase, or lineside cameras, secondary patterning is not usually a huge problem.

Secondary patterns can be distracting but several options exist to minimize the problem. First, for broad (e.g., "theme") area painting, select tiles that lack strong contrasts in color (appear highly textured) as these produce very noticeable secondary patterns. Here, selection for color is more important than texture; save highly textured tiles for areas close to the track. Use the Texture scale 'Ctrl [/]' set high or at maximum to reduce the frequency of repeat of the pattern. Regularly change the Texture direction '[/]' and Scale settings as the tile is painted over broad areas to break up the secondary pattern, although adjusting Texture scale Ctrl '[/]' too far downward may not be helpful. Another option might be to create a complex ground pattern mixing several different tiles and applying this to the broader areas using the Copy and paste tool. Finally, realize that covering the ground with a high density of objects (such as lots of trees) can effectively obscure the secondary pattern (of the forest floor).

[edit] Water Features

Of all the various landforms one can create, water features hold the greatest potential for enhancing scenery along a Route. And water is superbly rendered using the water tools found in the Surveyor Topology Tab. Three tools are provided: Add water 'W', Adjust height 'E', and Remove water 'Q'. An input box for setting water surface height is provided. The Add water tool paints a surface in the same manner as coloring, described elsewhere. However, the water surface has unique properties, the most significant being transparency and reflectivity. Improvements in rendering of these properties with each successive Trainz version has been a major contribution to making a realistic CGI.

Painting water establishes a level surface at the setting in the water surface height box. Expanding this surface always maintains the same height as long as you begin painting from the existing surface (no need to adjust the setting). The Adjust height 'E' tool adjust the entire connected surface all at once, but does not change any other water surfaces on the map not connected to the one being adjusted. Thus, you can create a series of lakes at different elevations so long as the water surfaces of each are not connected. Determine this independence by selecting Wireframe View in the Display Menu (or pressing F9). This displays the baseboard in white and the water surface(s) in grey, removing all the painted surfaces. Use the Remove water 'Q' tool to disconnect close-by water surfaces that you wish to set to different heights. Working upstream of a long river, you can progressively raise the surface of segments at points with rapids, waterfalls, or dams. Just be sure the water surface is broken at these points. An oddity built into the Adjust height tool is that if you hold down the Shift-Key while raising or lowering the water surface, the surface becomes bendy, going up or down within a limited area, no longer representing a level surface. If you bend it too much, it snaps back to a level surface at some new height. There must be a use for this?

[edit] Water Color

Because the water surface is transparent, the color of the water feature and/or the nature of the bottom can be established by coloring the underlaying board surface. Creating muddy water or an algae-colored pond then becomes a matter of selecting an underlying color producing the desired result. The intensity of these underwater paints is controlled NOT by the distance between the water surface and the baseboard (water depth), but by distance from a shore. Over a baseboard without coloring, water has a color based on settings as described in the next paragraph; the board grid shows through for a distance up to about 40 m (130 ft) from a shore. Beyond that, the bottom fades away (no matter how colored) and water color darkens. This property is one of the great improvements made between TRS2012 and TRS2019 versions. Essentially, realistic deep water is built in and need not be rendered by painting the bottom with progressively darker color or physically lowering the surface (which never worked anyway). Thus, the offshore bottom need not be any deeper than the nearshore shoaling. Ocean depths are not rendered by grid depth or coloring; you can bother to color or not color deep water bottom. See "ocean and large lakes" below to learn how to tweak the color of deep water on your route.

Open up the Edit Menu (top menu bar, second from left) and pick Edit Environment from the list. This opens up a small window titled Environment - Lighting. Here you can set the color of your water features (one setting sets all). Make sure the time dial is pointing straight down (noon) and click on the green dot below it. Selecting any dot turns on the tools that establish the color ambiance of the Route at the time of day represented by the position of the green dot, but starting with noon is most influential for the daylight hours. The three boxes to the right of the cloud preview determine what the color dials will influence; the bottom box is water color. Selecting that box and then tweaking the red, green, and blue color dials allows setting water color over a wide range. The vertical slider to right sets the overall brightness of the scene (not just water). A well illustrated description of setting water color is found at Environment Tools - Water Colour.

[edit] Water Surface

In addition to transparency and reflectivity, the water surface in Trainz has a third unique property: that of water surface condition. Nine different "sea state" conditions are available under Edit Environment in the Edit Menu. Select Environment (sun rising icon) and note Water (2nd from bottom). Click on the text window to produce a list of available options. If your water surface is showing behind the Environment - Environment window, you will see instantly the effect of changing the water surface property from "glassy" through "rough". The setting will apply to all the water surfaces created on your route, so you may have to compromise if you have both ocean and inland lake/pond water features. Click on "X" (top right)—your selection is saved and the window closed (see also Environment Tools - Set Water Surface).

[edit] Rivers and Streams

Several options exist for rendering a river or stream on a route map. The most direct and perhaps easiest to create is a narrow, linear basin with a water surface. Painting the water surface confined by a topography of banks and detailed with appropriate bank and bottom coloring tiles produces a very satisfactory aquatic feature that can be lined with trees, shrubs, and/or grasses. Important to remember in creating the course of the feature is to develop meanders and bends, minimizing long straight segments.

In a landscape of topographic relief (mountainous), extending a linear feature with the level water surface may prove impractical, requiring that the water surface be broken up into unconnected segments that can rise step-like as the stream extends upslope. A good example of how to "connect" these segments is provided in the MPS Route, "Sgt_Fury4449's Epic route" where a wild river is depicted flowing from tributaries and lakes down to a coastal estuary.

Creeks and small streams can be perennial (contain water year-round) or intermittent (flowing water present during the wet season). Dry streams might be created by a contrasting tile "material" representing sand, mud, or rounded boulders/gravel as a bed winding across the terrain beyond the banks. A number of stream spline objects are available to represent water, the splines presenting different widths and colors (search the Download Station for "stream" and "river"). For wider splines, first create the physical channel, lay the spline in, and then cover the edges by raising the banks. Narrow splines can be used in short segments where the water is just glimpsed within a dense riparian vegetation. If you do not set the spline height, the depicted feature will follow the ground surface (bed) you created.

[edit] Ocean and large lakes

Sea coasts and large lakes are extensive water features extending out to a distant horizon. Several baseboards out is sufficient, unless higher elevation views are anticipated (for example, a track laid well above the shore). Because depth does not influence the appearance of the water body (see "water color" above), the ocean or lake baseboard can be a level surface only a little below the water surface. Coloring the board is optional, except close to the shore where the map grid ("Grid (PBR)") is visible. If the "horizon"—the outermost baseboard—is kept to a line of baseboards oriented east-west or north-south, the appearance will be a natural one blending into the sky. However, if these horizon baseboards jog inward or outward, the sides of one or more baseboards (which are actually three dimensional blocks) will be seen ("World Edge" effect) from some points on the land. Pushing the horizon further out will reduce this obvious break in the horizon line to some degree, but not completely eliminate it. Placing a far shore (or another land) or an appropriate backdrop can solve this problem.

It is possible to overcome the disappearance of bottom with distance from shore and, for example, create an offshore reef or shoal or just extensive shallow water with a unique bottom type or color. Choose an area to create this and raise the bottom to just above the water surface using the Height up 'U' tool set at low sensitivity. Then lower the area (Height down 'D' tool) to just below the water surface; the grid (or bottom color) will disappear. Now, click anywhere on the baseboard with the Add Water 'W' tool. This has the effect of resetting the display relationship between the water surface and the bottom for the entire baseboard. The shoaled area, without any shore, will reappear and can be colored as sand or mud. You can expand the shoal with the Plateau 'P' tool set at high sensitivity and wide radius. Although it may appear that nothing is happening as you do this, clicking the baseboard with the Add Water 'W' tool will reveal the change you are making. Switching to Map View under the Camera Menu will show the bottom display as light blue for deep water (bottom not visible), light grey for visible but fading bottom, and dark grey (or some color if not "Grid (PBR)") for shoal bottom. Curiously, returning these areas to "deep water" will remove the shoal, but have no impact on the color scheme displayed in Map View (in Trainz Plus; could be adjusted in earlier Trainz builds).

PencilTips.PNG You can spot in tiles with white (for example, "ALWater 2") to mimic waves breaking along a shore. Other mostly white paints can mimic crashing waves or rough water as shown in the example from Kahiki by Sourtoe. Try different tiles (look for stream or waterfall tiles) to achieve the desired effect.

[edit] Water Effect Layer

The Water Effect Layer has been introduced primarily for Surveyor 2.0 and is available in TRS19 SP4. However, a route can only have one system for rendering a water surface—the traditional "legacy water color" or the water effect layer—and functionality of the latter is presently limited. Converting a route from legacy water color to Water Effect Layer is accomplished using the Edit Environment-Environment window in the Edit Menu, clicking the icon to the right of the select a water surface type. Converting requires a download and the result is removal of the legacy water surface and replacement with an inky black water surface. Instructions for proceeding are sparse at best. Converting back to the traditional water surface entails removing the water effects layer and then repainting water surface(s) everywhere on the route.

[edit] Problems

The Get Height 'G' tool of the Topology menu is essentially non-functional; an elevation will sometimes be obtained (once only if Plateau 'P' is set and 'G' is typed), but the value is not the current cursor point on the baseboard but some previous value selected. The Plateau 'P' tool serves to obtain the elevation of a point on the baseboard in TRS2019.

Bug.png

Using the shortcut key, cap 'S', will crash the program in versions of TRS2019 earlier than Build 114800. Problem is fixed by updating to TRS2019 SP4.

Bug.png

The Edit Environment tool discussed above to set ambient brightness and water color lacks a "save" button. To complete your actions and presumably "save" your settings, you can only close the window. However, this action alone will NOT save your settings. Before closing surveyor you must make some other change to the map board, then save the session.
