Hello guys!
As always, here is only one place where I can find answer!

So, here is problem
I need make moving fire from ground to box, when path sop collide with box sop i need transfer attr temperature and grow points with this attribute for ignite red points with fuel attribute over the time.
All this stuff i try to make in solve sop for animate this process.

For this i need create group for new fuel attr points but I don't know how to do this correctly…
