button_target is a brush entity available in all GoldSrc GoldSrc games. This entity allows you to create a solid that acts like a button when shot. It won't move, but will change texture and activate its target.

Key Values


Name (targetname) <targetname>
The targetname that other entities refer to this entity by.
Render FX (renderfx) <choices>
Render FX mode to use, for special effects.
Value Description
0 Normal
1 Slow Pulse
2 Fast Pulse
3 Slow Wide Pulse
4 Fast Wide Pulse
5 Slow Fade Away
6 Fast Fade Away
7 Slow Become Solid
8 Fast Become Solid
9 Slow Strobe
10 Fast Strobe
11 Faster Strobe
12 Slow Flicker
13 Fast Flicker
14 Constant Glow
15 Distort
16 Hologram (Distort + fade)
Render Mode (rendermode) <choices>
Render Mode to use.
Value Description
0 Normal
1 Color
2 Texture
3 Glow
4 Solid
5 Additive
FX Amount (1-255) (renderamt) <integer>
Controls transparency when using another render mode then normal. 0 is completely invisible, and 255 is opaque.
FX Color (R G B) (rendercolor) <color255>
Color to use by the specified render mode.
Also used on brush entities to control the speed of scrolling textures; see func_conveyor for more information.

Master (master) <string>
Name of a master entity.
Minimum light level (_minlight) <string>
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>
Used to define a target to sample lighting from.
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.
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)
zhlt_hidden (zhlt_hidden)
zhlt_striprad (zhlt_striprad)
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.
