UV Map editing

Needed a tool to edit UV maps once remeshed with poly groups… as you see in picture they all have the same pattern , need a way to manipulate nested uv

Maybe clone the mesh before (with facegroups) to have a copy - then reproject only the facegroups back to the remeshed mesh.

Need to keep the objects separated.
Or edit he material map to have different textures within the same map (which is usual method)
