==KIND: TUNNEL==


===Description===
Road and rail tunnel variable length splines. These allow the spline to be placed below ground and usually require an integrated initiator and termination mesh as a tunnel entrance.


===Container Structure===
A well formed tunnel kind has the following container structure:

===TAGS AND CONTAINERS===
The following tags are further defined in Chapter 5:

;kuid
:Generated automatically by [[Content Manager]].

;trainz-build
:Automatically set to 2.9 for 2009 assets.

;category-class
:Should be "TT” - Tunnel. See the "Track" section of [[Category Class]].

;category-region
:See [[Category Region]] for a list of valid category-region values.

;category-era
:See [[Category Era]] for a list of valid category-era values.

;username
:Asset username. This will be the name that appears in the surveyor menu.

;kind
:Must be "bridge". <font color="red"> ERROR ??  should be "tunnel"?</font>

;rgb
:This value should be left as default.

;height
:Height from the track level to the base. Must be a positive value in order to place the tunnel under the ground.

;bridgetrack
:Kuid of the track type to be used.

;kuid-table
:The kuid of the track\road used in the asset should be present here, as should those of any other referenced assets.



===Additional Tags===

;bendy
:Switches how track is bent on corners, set as 1 allows the mesh to be deformed as the spline is bent around corners.

;carrate
:Defines traffic density on road (minimum seconds between each car generated). 0 = No traffic. Number must be greater than 3.

;casts_shadows
:Toggles whether the shadow model is displayed.

;endlength
:Length in metres of the initiator and terminator models.

;grounded
:Height in metres for the road to be offset from terrain.

;isroad
:Specifies track is a road with cars, set to 1 for cars to appear on road.

;istrack
:0 = This is not rail tracks.
:1 = This is rail track. ('''isroad''' must be '''0''' or omitted)

;length
:Length of track segment in metres

;repeats
:The number of times the mesh is placed between spline points

;shadows
:Leave as default 0 (unticked box).

;upright
:Specifies whether the bridge "legs" point vertically, or perpendicular to the spline.

;visible-on-minimap
:Specifies whether the object\track is displayed on the minimap.

;width
:Width of track mesh in meters.

;bridgetrack
:Kuid for the type of rail or road used on bridge.

;height
:Height from the track level to the base, should be negative.

;trackoffsets
:Distance in meters the rail/s are attached to the center of the spline. Any number of tracks can be attached to the spline, only splines with the same track offsets can be connected together.

;divider
:Name of the model to use as the middle bridge section. Placed in subfolder with same name. dont-flip-terminator Terminator model isn't mirrored on one side.

;hidden
:Prevents the spline from being rendered.

;initiator
:Name of model to use at start of bridge, placed in subfolder with same name.

;invisible
:Specifies whether the object is invisible in driver.

;terminator
:Name of model to use at end of bridge, placed in subfolder with same name.
