I don't plan on actually having this many objects in the game, but I noticed when toying around that after 130 of my belt objects are in the scene things break down, specifically the rigid bodies all freeze (the bananas) and ray casts on a number of my belt objects quit working.
I can still add more belt pieces but new ones can't be clicked.
Where it gets hilarious: all those frozen bananas are still collecting the forces acting on them. If I delete enough belts to go under 130 they fly off with all that accumulated force and all the belt objects work normally again.
Appreciate any tips or links
