Is there a way to have particles spawn and die only within the confines of a mesh?

Hey thanks man. I’ll try this out, but I’m anticipating it won’t have the nice look of random floating particles that an actual particle effect would have. Know where I can find that texture file? I really wish the cascade “kill box” worked like they say it’s supposed to. That would solve all my issues but for some reason they didn’t make sure it worked right. Didn’t work right in UDK either.
