I am trying to flatten by uv's a mesh that I can retopologize then morph back the retopo. The reason is I have a marvelous designer model with lots of folds, I spoke with an artist that uses 3ds max, but I am not going to go use that. I found a the tool he used in max called textool which was ported over to blender 2.79 and then someone make it work for blender 2.8. it does in fact flatten the mesh from uv's which uses a shape blend. I tried using retopoflow alpha I have but that won't work since the mesh is in this weird shape blend state. I could make it work using poly build but then the full problem is how to morph it back into its orignal mesh state.
Let me know what I might be able to do.
I did find this script on this site, but it doesn't seem to help this issue. Unwrap morph project.
here are some other things I found video on Creating Mesh from uv layout in blender(easy), this gets me there manually if i want to flatten to uv's which is fine, but the I need to morph back so. I found this Video on Blender 2.8 Shapekeys and morphing problem is trying to some how morph back the retopo.
if your puzzled what I am trying to do and don't mind looking at a maya video, this guy, Retopo geometry for animation, marvelous designer
