Help:Surveyor Topology Tools
The Topology Menu provides the tools for creating various types of terrain. In this section you will learn how to make hills, valleys, mountains, lakes and rivers.
Click on the Topology Tab (or press the F1 key) to open the Topology Menu. Here you will see a number of different tools that can be used to shape the terrain. Hold your mouse cursor over each one to see a short description as well as the appropriate Hotkey to press. To see the whole menu as in the iamge below, click on the “Advanced” button to expand the menu.
- The three top buttons allow you to activate the basic tools to raise and lower terrain.
- The knobs below that alter the area the tool will affect and the sensitivity of the tool.

Height up (U)
Use this tool to create mounds, hills and mountains. Click on the Height Up tool icon to change to Height Up mode. Move your cursor from the tool tab onto the 3D world and you will see a "circle of influence". Left click and drag your mouse around the 3D world to raise the terrain. Use Radius and Sensitivity to adjust the size and sensitivity of this tool. To adjust your view of the world as you mould the terrain, right-click on the terrain to move your camera focal point and use your cursor arrow keys to move the camera. Use Undo if you don't like the results you see.
Height down (D)
Use this tool to modify the terrain height. Make hollows, valleys, rivers, lakes and oceans.
Click on the Height Down tool icon to change to Height Down mode. Move your cursor from the tool tab onto the 3D world and you will see a "circle of influence". Left click and drag your mouse around the 3D world to lower the terrain.
Use Radius and Sensitivity to adjust the size and sensitivity of this tool. To adjust your view of the world as you mould the terrain, right-click on the terrain to move your camera focal point and use your cursor arrow keys to move the camera. Use Undo if you don't like the results you see.
Adjust height (A)
Adjust Height allows finer control of the up and down movement. Click LMB and hold then push your mouse away from you to raise the terrain. Click LMB and hold then pull the mouse towards you to lower the terrain. Generally used for finer adjustments. Use in conjunction with the Radius and Sensitivity tools.
Radius
Click LMB on the Radius Tool and move to either side to change the circle of influence. Move the dial right to enlarge the circle (HOTKEY “+”), left to minimize (HOTKEY “-”). The size of the circle determines the outer limit of influence of the tool. Whichever tool you have selected (highlighted) will be applied within the area defined by the circle.
Sensitivity
Click LMB on the Sensitivity Tool and move to either side to change the amount of height changed each time the circle of influence is affected. Move the dial right to make more sensitive (HOTKEY “+”), left to reduce the sensitivity (HOTKEY “-”).
Get height (G)
Select Get Height (G), then Click RMB on the side of a hill. Notice that the number in the Height Value field changes. You have captured the height of the terrain at the point your compass appears. Use in conjunction with the plateau tool to flatten an area to a certain height.
Use height (H)
Click on Use Height (H) then Click LMB to apply the selected Height Value to the terrain. The Use Height tool creates a plateau at your selected height and the radius of your cursor circle determines the amount of land that is leveled at one time. Click and hold LMB then move your mouse around the terrain to level out a broader section. This tool is not affected by the sensitivity dial.
Plateu (P)
Plateau (P) creates a plateau at the current height of the compass. Click LMB on the side of a hill to create a plateau at that level by raising or lowering the terrain.
This tool is affected by the sensitivty dial. Moving your cursor around over pre-existing hills will create a smoothing effect. Adjust the sensitivity to flatten/smooth areas quicker or slower.
Height value field
You can manually enter in the height to apply. Click on the number showing between Get Height and Use Height and manually type in a value. To apply the selected Height Value to the terrain, click on the Use Height tool then LMB on the terrain.
Add water (W)
Click LMB on Add Water (W) and paint the water texture along the desired area by moving your mouse around. The radius of the cursor circle determines the texture panel size.
Remove water (Q)
Click LMB on Remove Water (Q) and you then delete the water texture one panel at a time by Clicking LMB on each water panel.
Adjust water height (E)
Select the Adjust Water Height tool and Click LMB and hold (on the water texture) then drag your mouse forward and back, adjusting the water texture height until it is the appropriate height.
Add ground (X)
Select the Add Ground (X) tool. Click LMB in the void just off the edge of the baseboard to add another baseboard in that direction.
Delete ground
Click LMB on the Delete Section button. Then Click LMB on any baseboard section to delete it.
Advanced
The Advanced features menu can be opened and closed by using Shift-F1 or clicking on the Advanced Tab.
Displacement map
A displacement map is a grayscale image used to create an instant height map.
Direction
Move the direction dial in the directon you wish the grayscale map to be put down on the baseboard.
Threshold
Move the Threshold dial to increase the size of the height change set on the displacement map.
Select area (B)
Click on Select Area (B). Click LMB and drag the mouse to make a large square as shown below. The size of the square (or rectangle) determines the area that will be affected by the next operation.
Fill area (F)
Scroll through the Displacement Maps, then click on Fill Area (F). The terrain is instantly transformed into the shape determined by the grayscale images of the displacement map chosen.
Cancel selection (D)
Click LMB on Cancel Selection (D) to cancel the selection.
Get displacement (B)
Click on Select Area (B). Click LMB on the baseboard and drag the mouse to make a large square that covers an existing area of modified terrain. Now click the “Get Displacement” button and you’ll notice that a displacement map has been derived from the shape of the terrain. This can now be used to apply the same terrain effect in another area.
