"mesh-table" container (interior version)
The "mesh-table" container is a top-level config.txt file entry used by various Content Types. Refer to the "mesh-table" Container documentation for the standard tags - this document only describes the extensions available within the mesh table when it is used in a cab interior asset.
Most of the entries in a mesh-table for an interior will be cab controls. A cab control has a single value associated with it, which could be an input (e.g. a lever position) or an output (a dial or gauge position).

Supported Tags
Each mesh subcontainer supports the following tags. Each tag is shown here with its default value. Standard tags inherited from the normal mesh table are omitted for brevity.
tooltip-text "" tooltip-token "" limits 0,1 angles 0,0 kind "" collision-parent "" mousemode "" mousespeed 1 notches invert 0 notchheight onlight "" value 0.0 font "swiss" fontsize 12 fontcolor 1.0,1.0,1.0 fade-time 0.5
tooltip-text
- Type: String
- Desc: OBSOLETE: DO NOT USE. This text will be used in the tooltip that appears when the mouse cursor hovers over a cab control.
tooltip-token
- Type: String
- Desc: The name of a string table entry. The contents of the named string table entry will be displayed as a tooltip that appears when the mouse cursor hovers over a cab control.
limits
- Type: Decimal Pair
- Desc: Specifies the minimum and maximum values for a cab control or needle at it's two endpoints of movement. In the case of a speedometer, this would be the range of speeds it can display - 0m/s to 50m/s, for example.
angles
- Type: Decimal Pair
- Desc: Specifies the minimum and maximum extents of movement for a control or needle. For control types that rotate, these values are in radians[[1]]. In the case of a speedometer, this would define the amount of angular movement of the needle - a speedometer running from horizontal left to horizontal right may use -1.57 to 1.57, for example. If the cab control needs to move the other way, put the higher number first.
kind
- Type: Selection
- Desc: The type of control this mesh table element represents.
- Options are:
- animated-lever
- Operates like a standard lever, only uses a named animation instead of the angles tag for movement.
- animated-dial
- Operates like a standard needle, only uses a named animation to represent the gauge readout instead of the angles tag.
- collision-proxy
- This element type defines a volume within the cab where the mouse pointer will be considered to be over the cab control. Generally used in conjunction with an animated-lever. Name of the animated lever is defined in the tag collision-parent.
- digital-dial-spd
- Digital readout for a speedometer, and using speed units.
- digital-dial-prs
- Digital readout for a pressure gauge, using pressure units.
- firebox
- The animated firebox in a steam locomotive.
- lever
- A standard lever, often used for throttle and brake controls. Requires the user to click hold and move the mouse to move the lever between it's notches. This control will stay at any notch position when let go.
- light
- A light glow / overlay - this mesh is hidden when the light is off and shown when the light is on.
- needle
- An analogue gauge needle. Can be used to implement many different types of gauges.
- pulllever
- Like a lever, only sprung to return to it's initial position when the user lets go of the control. Useful for horns.
- pullrope
- Like a pulllever, only with linear (not rotational) movement.
- switch
- This control requires only a single click to move between it's two endpoints. It is better suited than a lever to small switches and buttons.
- button
- Similar to switch but requires the mouse be held down to keep the control active. I.e., press and hold the mouse button to push the control down, release the mouse and the control will return to the off position.
collision-parent
- Type: String
- Desc: A mesh of kind collision-proxy must specify a collision-parent - the mesh it is a collision proxy for. This is the name of another control in the mesh-table.
mousemode
- Type: String
- Desc: If set to "exact", will require the mouse to be positioned over the geometry of the control precisely to activate it. Otherwise a bounding volume is used. This is useful for large controls which would otherwise block access to smaller controls.
notches
- Type: Decimal List
- Desc: Specifies the positions of the notches for this control. Notches are discrete positions within the movement of the control where the lever can be stopped. If a lever does not have notches, it can be positioned at any location. There are two common uses for notches. Firstly, they can be used to define a control which has a number of discrete positions which mean specific things (e.g. a brake valve). Secondly, they are used to define pre-set discrete values that a control can provide (e.g. a throttle lever). A typical US diesel 8 notch throttle would have something like "notches 0.0,0.125,0.25,0.375,0.5,0.625,0.75,0.875,1.0", specifying nine positions (for 'off' and notches 1 thru 8).
invert
- Type: Boolean
- Desc: Invert mouse movement for this control. If the control moves the wrong way compared to the mouse, change this setting.
notchheight
- Type: Integer List
- Desc: Specifies the importance of the notches for this control. This affects how the graphical overlay draws each notch. This is useful for a combined brake and throttle controller, or any other control where you want to mark a specific position relative to the others. This should have the same number of values as the 'notches' list.
- Three styles are available:
- '1' configures this bar to be a standard length and width bar.
- '2' configures this bar to be shorter in length, and is often used for intermediate positions.
- '3' configures this bar to be standard length, but thicker in width. This is often used for marking a specific position.
onlight
- Type: String
- Desc: Specify the name of a light kind mesh which is enabled when this switch/lever is in the on position, and disabled when it is in the off position.
value
- Type: Decimal
- Desc: Specifies the initial value for this control. For a lever or other input device, this will specify the initial position of the control before the user moves it.
font
- Type: String
- Desc: Font name to use for the readout of a digital control.
- Options are:
- swiss (Default option. Renders with arial in PC builds.)
- times_new_roman
- verdana
- century_gothic
- cordia
- courier
- helvetica
- arial
- comic_sans
- sans_serif
- impact
- console
- tohoma (renders using the Tahoma font on PC builds.)
- garamond
- These roughly correspond with Windows font names. Beware - not all fonts are available on all platforms, and where a font is not available, a different font may be substituted.
fontsize
- Type: Decimal
- Desc: Font size for the readout of a digital control. Default is 12.
fontcolor
- Type: Decimal Triplet
- Desc: RGB font color for the readout of a digital control. Colors are specified within the range 0.0 to 1.0, with 0.0 being black and 1.0 being full intensity. Default is 1.0,1.0,1.0 - white.
fade-time
- Type: Float
- Desc: The time, in seconds, for a "light" control to fully switch on or off. Default is 0.5 seconds.
