func_trackchange is a brush entity available in all GoldSrc GoldSrc games. This entity allows you to create a rotating platform that will switch a func_tracktrain's path, used mainly with player-controllable trains.

Key Values

Minimum light level (_minlight) <string>

Targetname:

Name (targetname) <string>
The targetname that other entities refer to this entity by.
Travel altitude (height) <integer>
Altitude to ascend or descend (use negative values for the latter, or 0 to disable altitude change).
Spin amount (train) <integer>
This is the amount in degrees the track will turn on its way up / down.
Train to switch (rotation) <targetname>
The Name of the train that is using the track.
Top track (toptrack) <targetname>
This is the Name of the last path_corner in the upper track.
Bottom track (bottomtrack) <targetname>
The Name of the first path_corner in the lower track.
Move/Rotate speed (speed) <integer>
The speed in units/sec that the track platform will move. If the Rotate Only flag is set this will be the speed of rotation only.
Global:
Global Entity Name (globalname) <string>
Name to identify entity accross level transitions. Entities with the same global name will have the same status accross maps.

Flags

Auto Activate train : [1]
Relink track : [2]
Start at Bottom : [8]

Y Axis : [128]

Rotate around the Y axis.


Minimum light level (_minlight) <normal>
ZHLT family
ZHLT Light Flags (ZHLT 2.2+) (zhlt_lightflags) <choices>
Special lighting behavior. Only available if using Zoner's Half-Life Compile Tools.
  • 0 : "Default"
  • 1 : "Embedded Fix"
  • 2 : "Opaque (blocks light)"
  • 3 : "Opaque + Embedded fix"
  • 6 : "Opaque + Concave Fix"
Light Origin Target (ZHLT 2.2+) (light_origin) <targetname>
During lighting compilation, this entity will be treated as if its origin were at the target entity's origin. Requires an origin brush.
Entity to Use Model From (ZHLT) (zhlt_usemodel) <targetname>
Used to set the model to a different entity's model (bmodel, BSP, MDL, or SPR). The targeted entity will be moved before this entity to ensure proper loading. Requires an origin brush on this entity, as well as on the target entity if target entity is a brush entity.
Nonsolid (ZHLT) (zhlt_noclip) <boolean>
Disables generation of clipnodes for all brushes on this entity, except for clip brushes. The entity may still be solid to point traces (hitscans, grenades, etc) if the brush contents are set to solid.
Tip.pngTip:Always enable this for func_illusionary, unless skin is set to -16 (ladder); VHLT does not properly strip clipnodes for this entity.
Don't Render (ZHLT 3+) (zhlt_invisible) <boolean>
Treat all faces as if they were textured with NULL.
Tip.pngTip:Use this on triggers which use custom textures instead of AAATRIGGER or NULL, such as ladders.
Custom Hull 1 (VHLT+) (zhlt_hull1) <targetname>
Custom Hull 2 (VHLT+) (zhlt_hull2) <targetname>
Custom Hull 3 (VHLT+) (zhlt_hull3) <targetname>
Which named info_hullshape entity to use for the specified clipping hull.
Mins/Maxs (VHLT+) (zhlt_minsmaxs) <mins vector + maxs vector>
Override this entity's bounding box.
zhlt_transform (zhlt_transform) <???>
Never visible (VHLT+) (zhlt_hidden) <boolean>
Don't create marksurfaces for this entity, resulting in it being treated by VIS as never visible.
Tip.pngTip:The _HIDDEN texture suffix does the same thing, but also works on world brushes, which are used for model lighting.
Strip lightmaps after compiling (VHLT+) (zhlt_striprad) <boolean>
Undefines the lightmaps for brushes on this entity after compiling, resulting in the faces being fullbright and not using up allocblock. Unlike TEX_SPECIAL, faces with zhlt_striprad will still affect bounced lighting.
Custom Shadow Color (VHLT+) (zhlt_customshadow) <color1>
If this entity casts shadows, the shadows will be this color instead of black. Can also be a single value, for monochrome.
Fake Lightmap (VHLT v33+) (zhlt_embedlightmap) <boolean>
Generates unique diffuse textures for all textured faces, then bakes lighting information directly into the generated textures. Primarily used to prevent translucent surfaces from "glowing", as rendermodes which support translucency don't render lightmaps on the vanilla renderer.
Icon-Important.pngImportant:The resulting textures will be renamed to have the prefix __rad; as such, any unique attributes will be lost.
Downscale Fake Lightmap (VHLT v34+) (zhlt_embedlightmapresolution) <integer>
Downscale texture created by zhlt_embedlightmap this many times.
ericw-tools
Note.pngNote:If any of the booleans are set in worldspawn, they can be disabled per entity by being set to -1.
Cast shadows (_shadow) <boolean>
Cast shadows from this entity. Implies _shadowself.
Self-shadowed (_shadowself) <boolean>
Cast shadows from this entity onto itself.
Shadow world only (_shadowworldonly) <boolean>
Only cast shadows on world, not models.
Smooth shading (_phong) <boolean>
Enable smooth shading between faces which are less than _phong_angle.
Autosmoothing angle (_phong_angle) <integer>
Angle to smooth; default 89. Set to 44 to match QRAD/HLRAD defaults.
Maximum light level (_maxlight) <normal>
Minlight color (_mincolor, _minlight_color) <color1>
Color of _minlight. Also accepts color255, provided at least one value is greater than 1.
Minlight only (_lightignore) <boolean>
Only receive lighting from _minlight
Disable backface culling (_mirrorinside) <boolean>
