== 0 - Normal ==
Brushes are lightmapped and opaque, regardless of if they have {{code|{}} textures. {{code|renderamt}} and {{code|rendercolor}} are unused outside of [[func_conveyor (GoldSrc)|scrolling textures]].

== 1 - Color ==
Allows sprites to be tinted with {{code|rendercolor}}. Same as texture on brushes and MDLs.

== 2 - Texture ==
Enables translucency via {{code|renderamt}}, and alpha-tests {{code|{}} textures on brushes. Causes brushes to be fullbright.

== 3 - Glow ==
Only valid on sprites. Like additive, but renders the sprite at the same size regardless of distance from the camera.

== 4 - Solid ==
Same as Normal, but alpha-tests {{code|{}} textures on brushes. {{code|renderamt}} 0 is treated as invisible, but all other values are full opacity for non-alphatested texels.

== 4 - Additive ==
Renders the sprite, brush, or MDL using [[additive]] translucency ({{code|[https://registry.khronos.org/OpenGL-Refpages/gl4/html/glBlendFunc.xhtml glBlendFunc(GL_ONE, GL_ONE)]}}). {{code|Renderamt}} can be used to reduce opacity.
