I’ve tried installing UE5 on a different PC and building the same solution, but I still get the same result of physics objects getting stopped once they touch another mesh. But it works as expected in UE4.
If you got it working in UE5 could you possibly send me your .uproject file so I could try it out?
EDIT: The closest I can get this to working is by cranking up the speed variable for the belt. The objects fly down the belt but then end up all jittery once they’re off. But if I want a slow-moving belt, it can’t be done - objects get stuck to the belt. Testing this on two different PCs and getting the same unintended results leads me to believe that something has changed between UE4 and 5.
