WorldPosition Rotation on nanite breaks shadows.

WorldPosition Rotation on nanite breaks shadows. I have attached an image that shows my material for a rotating fan using world position offset… It works fine for non nanite. Works with nanite as well except the fact that the shadows do not work fine on nanite…

The shadow method is virtual shadow maps. I have not tested otherwise.

Any idea if there is a work around or if this is a bug that needs to be reported?
