Back from hollydays, I'm at some Momentum test again. Does anybody knows how the States are working with Momentum ? I've tried the classic State+State Machine combination to change the Mass of the particles from 0 (State 0) to 1 (State 1), but Momentum seems to ignore it.
I can see a State Attribute in the SetRigidBodyAttributes, but I don't know how to use it. Thank you !
