`env_bubbles`

env_bubbles is a point entity available in all GoldSrc games. It creates an area of rising bubbles.

Key Values

Targetname:

Name (targetname) <targetname>: The targetname that other entities refer to this entity by.

ZHLT:

ZHLT Light Flags (ZHLT 2.2+) (zhlt_lightflags) <choices>

Special lighting behavior. Only available if using Zoner's Half-Life Compile Tools.

Light Origin Target (ZHLT 2.2+) (light_origin) <targetname>: Used to define a target to sample lighting from.

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:Always enable this for func_illusionary; 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:Use this on triggers which use custom textures instead of AAATRIGGER or NULL, such as ladders.

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.; Important: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.

Bubble density (density) <integer>: This is the density of bubbles spawned.

Bubble frequency (frequency) <integer>: The higher the value here, the greater the frequency bubbles will appear at.

Speed of current (current) <integer>: The higher this value, the more bubbles drift in the direction specified by the entity angle.
