Particle System Operators/render animated sprites

Render Animated Sprites

This render type renders the particle as a sprite, a simple quad. Depending on the .vmt parameters and renderer settings, this can be a camera facing sprite, a vertically, horizontally, or per-particle oriented sprite.

---

Animation Rate [float]

Determines the framerate of the animation sequence if the material has one. By default, 1.0 will map to playing the entire sequence length over 1 second.

Animation Fit Lifetime [bool]

If set, the animation will map to the lifespan of the particle (not currently functional)

Orientation Type [integer]

0 = Camera Facing

1 = Rotates on Vertical Axis but otherwise faces camera.

2 = Horizontal

3 = Per Particle Normal Orientation (requires material have $orientation 3 set)

Orientation Control Point [integer]

(not currently functional)

Second Sequence Animation Rate [float]

Determines the framerate of the second animation sequence if the material has one. By default, 1.0 will map to playing the entire sequence length over 1 second.

use animation rate as FPS [bool]

If set, treats the animation rate setting as Frames Per Second. Useful in combination with Lifetime from Sequence initializer to match framerates to lifespans.
