ParticleSystem.TextureSheetAnimationModule.speedRange

Descripción

Specify how particle speeds are mapped to the animation frames.

If a particle is travelling slower than the minimum speed, it uses the first frame. If a particle is travelling faster than the maximum speed, then it uses the final frame. For all other speeds, the particle chooses a frame based on how far between the minimum and maximum value its speed is.
