If I set a bumper car collision with SetObjectShapeConvexHull( objID )
They just fall over but SetObjectShapeCylinder( objID, axis ) on the other hand works quite well
https://forum.thegamecreators.com/thread/223110?page=2
and the test from blinkok from my thread above definately shows the collisions dont work proper with
convexhull collision shapes using a plainobject but works better with a box object.
