Mesh gives hard work

[a_mattano]

OK, Dear developers. I use Rhinoceros for creating cars, sailboats and game assets. And later I convert surface (NURBS) to poly meshes. Usually I do a manual unwrapping and import it to Painter but takes me a lot of time.

DESCRIPTION
I take out the UV mapping from the enclosed mesh and import it to Painter 2019.3.0. Painter is unable to unwrap correctly.

SEVERITY
