Velocity

3D Mask - Depends on the velocity of a Particles

For this mask to be effective, Particles needs to have a changing velocity. For this apply some Field over them.
On the example image, all particles are colorized by a Red Colorize then masked by a Velocity Mask.

Some modifiers, like Colorize Function directly have a mask inside of them.

Variables:

Minimum Velocity: Minimum velocity of the velocity
Maximum Velocity: Maximum velocity of the velocity

Python
