hi, I tried to define a boudingVolumn box by a known coordinates, like [X,Y,Z,halfx,0,0,0,halfy,0,0,0,halfz]. It did not work unless the rotation part of root transform matrix was untoched. That part looks not like a simple y-up to z-up rotation. So Im wondering whats happening in this rotation part.
