Hey gang,

I've got a very simple particle system using instanced geometry that has gravity and collides with a plane and comes to a stop.

What I want to do next is have each geometry object fade out when it comes to a stop. I've thought of trying to use a collision event, or just to script when the velocityPP = 0, but the thing is when I change the transparancy value for one, they all fade out since each instance uses the same shader.

Can anyone think of how to do this?
