Hail Setup

This setup is using instanced nParticles. Upon collisions the particles emit a new instanced nParticle for impact debris. All the custom attributes are located on the particles for easy editing:

~ scale per particle.
~ rotate per particle.
~ fields per particle -- gravity, wind and turbulence.
~ collision emission controls -- number of pieces, scale and scale gain (based on original), collision velocity, velocity gain, velocity random and position offset.
~ impact debris controls -- rotation speed falloff, fields falloff and velocity falloff (to freeze particles).
