- Color
(color)<color255> - Dust color.
- Opacity
(opacity)<float> - How transparent the dust is, on a scale from 0 (invisible) to 1 (fully visible).
- Emitter Lifetime
(emittime)<float> - How long to spread dust before stopping. 0 = never stop. This entity will not remove itself automatically once it stops emitting.
- Particle Lifetime
(lifetime)<float> - How long a single dust sprite can stay around for.
- Spawn Rate
(spawnrate)<float> - How many dust sprites to spawn per second.
- Minimum Random Speed
(minspeed)<float> - Minimum speed dust sprites can move at in a random direction. They will lose speed over their lifetime.
- Maximum Random Speed
(maxspeed)<float> - Maximum speed dust sprites can move at in a random direction.
- Minimum Directed Speed
(mindirectedspeed)<float> - Minimum speed to apply to dust sprites, in the direction specified by Pitch Yaw Roll
(angles). - Maximum Directed Speed
(maxdirectedspeed)<float> - Maximum speed to apply to dust sprites, in the direction specified by Pitch Yaw Roll
(angles). - Start size
(startsize)<float> - Size of the dust sprites when they first spawn.
- End size
(endsize)<float> - Side of the dust sprites when they get close to de-spawning.
- Spawn Radius
(spawnradius)<float> - How far away from the entity the dust sprites can spawn at.
