Really odd colliders that return true for CollisionFilter.IsCollisionEnabled won't collide. Layers have values but are not set to collide, colliders have the same >0 group index. Except they do collide when using Havok. Doesn't seem to matter how I create the collider, conversion or manual. I am using sub scenes, and the colliders are by default prefabs from the sub scenes. I tested with just replacing the colliders on instantiation with manually created ones to see if that made any difference but it didn't. Sort of at a loss, what seems likely to cause this?
