Transfer Maps for new UVs
Until the time of writing we can't preserve the strokes position with imported maps so if we change the UVs of the mesh the imported maps won't follow but If somehow we could use Projection menu to project the baked map such as Albedo using the 2D view of painter to project them directly on UVs then we can change the mesh UVs and import the mesh again and this time (preserve strokes positions on mesh) works perfectly fine. That's it we transfers map without any artifact and hard work which nowadays workflows such as maya transfer maps have.

Why no one voted! I think it's a pretty much important idea since transferring maps are a pain these days did I explain the idea clearly!?
