Physics control componet does not work properly when the parent mesh is in right hand coordiante system?

Hi. :grinning:

I come across a problem when using physcis control component. I have two physics bodies A and B jointed by a physcis constraint. B is attached to A. I set the scale of A to be (1,1,-1) and B’s relative rotation to be (0,30,0). The physics is set to only affect B. When the game begins I get the relative transform of B with respect to A and then create a relative control to maintain the relative rotation between A and B.

I think this should make B remain its initial rotation. However, the result is not so. The physics control component rotate B as if the scale of A is (1,1,1). I am not sure whether this is a bug or a conscious effort. Do I miss something? :confused:
