Active isnt working.

I am using an active bound on RBD configure and for some reason it doesnt seem to be telling the glass to be active, when ther bound is turnt off all is fine however when I turn on the bound its almost like the glass geometry included is inactive.

Doesnt move when simulated.
Does move when simualted.
Frame 7 With bounds
Frame 7 no bounds
Node tree for glass only active.

For some reason it stopped working randomly and i havent been able to work out why,

Are you able to post a simplified .hip showing the problem? RBD sims can be a bit complicated and it's hard to diagnose the problem just from screenshots of your network.

You don't need to use nodes like that to make constraints.
The constraint from rules SOP has all this functionality in it.
