Here is a screen capture of the water wheel building when I import the OBJ into 3D Coat for UV Mapping. I get this mess. It looks to me as the normals maybe flipped. But when the model is imported into Blender by the MOI3D Blender Import/Export addon/plugin/script, I check for flipped normals and all are showing BLUE. No RED faces on the outside of the mesh.




I can only get the mesh UV'd properly if I retopo it in Blender via Quad Remesher and doing this I lose most of my filets and chamfers.

Is there another way to UV MOI3D models other than 3D Coat?

AND NO, I do not have or want substance painter.

This only happens if I use texture maps. If I use Vue's shader materials which requires NO UV mapping (and not their image based textures ) everything if fine. But for most architecture I refer image based textures (bricks, walls, shingles, rust, etc).

Cheers
