Hi,

I'm trying to have particles switch groups depending on the HITNUM variable. For some reason it resets itself and never get higher than 1.

Any idea what's going on??

Thanks!

By default hit attribute, @hitnum, will be zeroed out before collision detection is performed.

There is two way (may be more) to fix this.
One is POPWrangle:

You can also do this process using only POPWrangle without any popgroup and popcolor.
