hey Adam.. I ran into this very problem on a previous project and it anooyed me to no end, especially when getting in tight on a shot of the ground.
I seem to remember that the min max speed or velocities thats usually set to 0 and 100000 were the culprits..
As soon as a I brought the ranges within the actual speed as defined in the emission ppg, the collisions worked..
Also made sure to check off. Use size for collisions.
If that doesn't do the trick, lety me know, and I can dig back into that old scene and get the right settings for you..
I was attempting the very same rain type shot.
I thought that I would need a scripted particle event, but it turns out not to be the case.
Adam
