merge vertex collapses mesh to single vertex

noface789

Beginner here, I'm trying to merge the vertices on this mouth but everything converges on 1 vertex. I tried hiding the faces to get to the vertex that was causing the problem and merged that one first before merging the rest, but it still causes everything to collapse to that vertex. Any ideas what might be the issue?

Depends on the software you're using. Which is what?
It's best to put the software name into your thread title, so people who know that software will be drawn into your thread.

Yes, please do this ^

I can't tell from your picture what vertices you are trying to merge since you're not showing the selection. In any case, merge vertex in maya has a tolerance setting- it controls the distance of the merge. Setting it too high has unintended results like this, or accidentally using merge vertices to center which will always collapse to the center. I set merge vertices to default at 0.001 since I nearly never want to do something like collapsing the outer loop along the mouth there.

Wow can't believe I forgot to do that. It's Maya 2017. But yeah throttlekitty you solved the problem, I had the threshhold turned up since I was having problems vertex snapping earlier. It's always the simple things...
