I have an edge attached to 3 polygons.. I thought this wasn't possible!

Anonymous · ‎09-12-2015

Hi folks. I have a model with an edge that is attached to three polygons. According to the docs, this shouldn't be possible. The reason I noticed it was because of some strange UVW unwrapping I saw after defining my seams.

I'm going to try and detach one face and resolve the issue, but is this a bug, or is this a legal object? If so, what's the best approach to resolve this? Maybe edge splitting or something? I'm looking into those options now.

Best regards,

Are you sure it is attached to all three? Try moving a vertex at one end to see.

Thanks for the reply! Yes, I checked that. In fact, I started off by selecting one vertex, verfying the modifier panel showed only 1 was selected, and confirmed the behavior when I moved it. I have since sliced up the geometry to correct this oddity, but it definitely happened. I believe I used the 'target' vertex tool to connect some of the polygons which may have led me to this situation. It led for a strange UVW unwrap, so I was interested if anyone else had encountered this. (This is with 3ds Max 2015, latest patches, BTW).

Cheers!

This is strange. I tried to replicate this. The verts will of course weld at one end of the "edge", but won't weld the verts at both ends, which would make it a single 3 way edge, as opposed to two coincident edges.
