Determine the size of the individual Particles
Randomly scales all of the particles in a group.
Tints the whole group a color. If particles are really dark or reflective, tint will not affect model and it is best to adjust the material settings.
Controls the transparency or visibility of the particles in the group.
Controls the Rotation of the individual particles in the Particle Shape.
If there are random parameters, such as Random Rotation used, this generates a new random instance.
