Description

Blender 2.69

When two rigid bodies has distinct collision group they are supposed to not collide. It works ok except when they starts intersected , then the bodies are put separated, it is an undesired behavior

it looks like when the rigid bodies are intersected at start, they come to be in the same collision group i dont know why

Essentially, if we cannot determine if a collision should happen (because the KX_GameObject doesn't yet exist), we allow a collision.
This patch adds a narrowphase callback to check the masks
