Use $FF < 100 in the Activate parameter?

Use $FF < 100 in the Activate parameter?

Or use: clamp($FF,1,100)

You can stop them from rotating by changing this : *clamp($TY,01,.1) to this : *clamp($TY,01,0). I'm not sure that's what you want, but it works for your setup. You might be better off trying to do your rotations inside pops though, since you'll have better control over what happens to it (ie, put the particles in a group when they collide and clamp the rotations).

Hope this helps
