World position offset affects dynamic lighting

Scene:one movable directional light and one movable sphere with material that rotates itself,
the problem is that the lighting seems to be rotating with it too.


WPO does not recalculate normals for You. You need to do it yourself and adjust vertex normals to match vertex rotation.

Thx for the answer,it works,but afterall it just uses too many instructions,I use parenting to rotate in the end.
