env_steam is a point entity available in all Source games. It is used to create a jet of steam, or heat wave distortion.

Keyvalue type set to normal on the left and heat wave on the right side.

The entity appears as a cone in Hammer, the shape indicates the direction the emitter outputs the particles (away from the point).

Bug:In

Alien Swarm, color is always white when the map is compiled with VRAD.

AltNames: This entity is also tied to env_steamjet.

Note:However, env_steamjet faces left instead of forward.

Flags

Emissive : [1]

Uses the value specified in rendercolor. If not checked, color is automatically determined by environmental lighting.

Name (targetname) <string>: The name that other entities refer to this entity by, via Inputs/Outputs or other keyvalues (e.g. parentname or target).
