Hello!
I have a problem with parent mesh rotation. Scene has two objects which will be rotation around center of bottom object. If bottom object placed on scene center then objects rotation correctly. But if replace bottom object then stranges begin... I create parrent mesh for object and try to rotate it. http://www.babylonjs-playground.com/#1KU02Z#0
Please tell me where I wrong?

you should now use setParent for this:
