UV Master issues

I’m trying to unwrap a decimated 25k poly mesh in ZBrush with UV Master, and it keeps giving me a really broken set of UVs… I attached a screenshot of what I’m getting now:

This is actually getting better, at first I just had one big flat triangle. I’ve tried everything I know to do to clean up the model, I even exported as an obj and reimported but I’m still having issues. This happens to me on occasion and I don’t know what the problem is. The last time this happened I just kept reimporting, decimating, and trying to unwrap until it finally worked. But I really didn’t change anything to make it work, so I have no idea how to fix it :confused: Does anyone know what I might be doing wrong here?

That looks like what happens when you give a spider mescaline!
Im not sure what you are after since I haven’t a clue what that actually is (but I like it for some reason!).
Can you give us more details on what you did, and what you did it to?

Hi Buffaloe,

Have you tried welding verts in your 3d package of choice? Sometimes when I’m using UV Master and it does something bonkers like this, it’s because I’ve got some stray verts or duplicate faces.

Haha, you’re right MealeaYing, it does look like that! :smiley:

And Johnny45, that seems to have fixed it when I export to maya, weld everything and bring it back in… which is odd because I tried using weldPoints in ZBrush after I exported as an obj and reimported and had a warning that I had 6 unmerged verts. Shouldn’t that have solved the issue? Not only that, but this was something that I had dynameshed which I thought closed holes and would have welded any stray verts in its retopologization. But either way, thanks so much for the fix, at least I’ll know what to do next time this happens! :smiley:
