env_smokestack is a point entity available in all Source games. It spits out a constant stream of smoke. You can place up to two env_particlelights near the smoke stack to add ambient light to its particles.

Keyvalues

Name (targetname) <string>

The name that other entities refer to this entity by, via Inputs/Outputs or other keyvalues (e.g. parentname or target).
Also displayed in Hammer's 2D views and Entity Report.

Initial State (InitialState) <choices>

Initial state of the entity.

• 0: Off
• 1: On

Spread at the base (BaseSpread) <integer>

Amount of random spread in the origins of the smoke particles when they're spawned.

Spread Speed (SpreadSpeed) <integer>

Amount of random spread in the velocity of the smoke particles after they're spawned.

Speed (Speed) <integer>

The speed at which the smoke particles move after they're spawned.

Particle start size (StartSize) <integer>

Size of the smoke particles when they're first emitted.

Particle end size (EndSize) <integer>

Size of the smoke particles at the point they fade out completely.

Emission rate (Rate) <integer>

Rate at which to emit smoke particles (i.e. particles to emit per second).

Amount of roll in degrees per second.

Base Color (R G B) (rendercolor) <color255>

The color of the particles.

Translucency (renderamt) <integer>

How much you can see through the particles.

Wind Vector (Wind) <vector> !FGD

Wind direction, not limited to any axis.
