UV coordinates shader for texture remapping in post

Fake Muse

I wonder if someone could provide an UV coordinates shader for Daz ( I would pay 15$ via Paypal).  So the texture coordinates of an object are represented by rgb values on its surface, allowing to render uv passes for texture remapping in post.
