Texture breaks at seam when converting nurbs surface to mesh

Hi,

I guess this has to be a known issue - when I convert surface from NURBS to Mesh the texture messes up at the seam like this:

panel.3dm (449.3 KB)

How can I fix or prevent this from happening? I know meshes have indices and I guess mapping the render mesh from nurbs surfaces to the new mesh throws them about. But I have no idea how to fix it.

Any help appreciated :slight_smile:

p.s. I have dozens of panels going over the seam so fixing them one by one is not practical. Even if I wanted to try that, I can´t see the new mesh mapping mesh in the UV editor.

Hello
this seems to be a bug, in Rhino 7 extract render mesh keeps the same UV.
