I have a few situations in which dynamic objects suddenly stop moving. There's no crash, some objects just freeze.
Apparently this can happen for example when objects leave the broad-phase bounds. This is fair enough and easy to fix.
However it also seems to happen in other cases for which I can't find a reasonable explanation, and that I can't find way a way to fix. A simple repro would be just creating an array of 64*64 non overlapping dynamic boxes in a scene (that's it, the scene is otherwise empty). If I create less boxes, they start falling under gravity as expected. But for 64*64 boxes they just freeze and can't move anymore no matter what I do.
Unless I missed something this doesn't seem related to the size of the broadphase.
Is there a parameter to tweak somewhere, that would make this scene work?
