hello,

I have created a particle effect that I would like to obtain a velocity pass for. I have set up a particle velocity take and I am using the rsmb.otl shader that is available from the exchange to get the vectors.

It works great for animated scene geometry but I cant seem to get much results when applying it to a particle system. I think it might be an issue of tolerance?

what is a good tolerance for the rsmb shader when dealing with quickly moving particles? Is there some better way to obtain this velocity info for my particles?

thanks for any help you may be able to provide

Adam
