There’s a confirmed issue when exporting SubD objects as OBJ files from Rhino 8. UV mapping is not preserved correctly, resulting in broken or distorted textures when importing into other software.
Bug reported here:RH-86792 - SubD OBJ UV mapping export issue
Temporary workaround: Convert SubD to mesh before exporting.
Please add any additional info or experiences to help get this resolved quickly!

Soaring Stars lab:
VertexWelding=Unmodified
By the way, VertexWelding=Yes does not weld uv mapping vertex.
