Yes, it's collision groups, because: `RigidBodyCollisionGroups::new_static();` return group with blacklist: `0b110000000000000000000000000000` And all_groups have membership: `0b111111111111111111111111111111` and ``` 189: ncollide_pipeline/world/collision_groups.rs self.membership & other.blacklist == 0 && other.membership & self.blacklist ==...
