Meteor example file

Particles fall from the sky and collide with a collision object, in this case a simple grid.

These single particles that have collided are placed in a group, and they are told to 'continue on course' so they are not themselves affected by the collision.

A half-sphere geometry is instanced to the particles for the purposes of the Split POP.

The grouped particles are then piped into a Split POP which then births even more particles after the collision, giving the effect of a meteor trail or fireball trail.

The split particles are birthed from the surface of the instanced geometry rather than simply the original particle.
