I seem to have the opposite problem of the answers here.
I want to copy the parent rotation vectors or world rotation vector to a child rotation vectors to force the child to follow the parent spin. I know that the child should follow the parent but it does not. The problem is the parent spins but the child does not. I have had this problem awhile now. It is different.

TIA.

Had used localRotation. This now rotates the child. I need to do the same for rigidbody.

But why?

Rigidbodies do not automatically rotate with their parent. If you need to use a Rigidbody, you would need to use a Joint to keep it in some way affected by it’s parent. But it sounds like you do not even need a Rigidbody.
