Just for share...

I'm not sure it would work, but you could try.
I tried and it "works". Extrude->Normal by 0 offset and in the Weld->Tolerance it was used 0.000:

Oh lord! I can't stop thinking about this issue. Smile

I see, it makes sense
I have to be wrong, otherwise we couldn't cut the mesh and create islands on AutoUV editor window.
I will take a look on this when I have time.

Hi micheus,
thank you for your caring and sorry for the late reply Blush

Yes, no doubt it works, but we find ourselves with a ring of small polygons around the edge of the welded faces, whose handling can be a bit unpractical. In addition to that, the two nearly coincident edge loops would be likely treated as hard edges, even where a soft edge is more appropriate.

Okay, let me know if you find anything on the topic. As I said a few days ago, there are 3D programs that perform edge/vertex weldings (a feature that I would like to see in Wings too, btw) without distrupting the geometry and/or the UV projection of adjoining polygons Smile
