Rotation from location to world

How to convert rotation from location to world? Sometimes one mesh is inside multiple parent node, how to get the absolute rotation in world?

There is a absoluteRotationQuaternion property for Mesh or TransformNode:

The property has getter only, how to set it?

I would multiply the world rotation quaternion you want to apply on mesh to parents inverted rotationQuaternion/absoluteRotationQuaternion. The result is the rotationQuaternion of your mesh. If you multiply by quaternions then first is rotated by second. So the inverted rotates in opposite directions, pretty much un-/derotate the aimed rotation of your calculation by parents rotation.
