Many people still get confused about what Bvolume to use for their sims, Bvolume is a helper object which wrap the geometry and determine the way the original object detect collisions, this is the first thing you have to create for an object to be in simulation.
In most cases “Auto” Bvolume will work fine, but if you are looking for better performance you should use Convex hull and there are 3 special cases:
– Capsule, for improving performance on spherical or cilindrical shapes.
– Mesh( animated), for use exactlly the original shape of the object, specially when this shape is animated.
– None, the object is still computing dynamic motion but doesnt detect collisions.
