Light:

Color + Brightness (_light) <color255 + int>

Custom Appearance (pattern) <string>

A string of english letters, like a sequence of piano keys, that define a pattern of brightness. a is 0%, m is 100%, and z is 200%. Updates at 10 Hz. Requires light to have a targetname.

Texlight (VHLT+) (_tex) <boolean>

Treat this entity as an light_surface, using the specified texture as the emissive texture.

ZHLT:

Copy lighting from (VHLT+) (zhlt_copylight) <targetname>

Copies the lighting from the named entity to the nearest lightmap luxel below this entity's origin.

Tip:To avoid having the copied lighting visibly affecting the brush lighting, put a 16x16x1 func_detail with zhlt_noclip enabled directly below this model's origin. Texture the top face with black_HIDDEN, and the rest of the faces with SKIP.

Note:Not compatible with entities using the effect flag EF_INVLIGHT.

Model shadows (UMHLT, SDHLT) (zhlt_studioshadow) <boolean>

Enable to cast shadows from MDLs found in the model KV.

Model shadow mode (SDHLT) (zhlt_shadowmode) <choices>
