Weird line when smoothing?

Introduction to Maya - Rendering in Arnold

This course will look at the fundamentals of rendering in Arnold. We'll go through the different light types available, cameras, shaders, Arnold's render settings and finally how to split an image into render passes (AOV's), before we then reassemble it i

I've got a fairly simple poly head mesh that seems fine when it's blocky, but gets weird when I smooth it. Any ideas what's going on?

That is strange. Does it render like that? Is it an actual hole in the geometry or some sort of visual error?

If it's an actual hole, I would guess that some vertices around the mouth need merging.

Yeah, that's what I thought might be the problem, but it doesn't show when rendering, and the line is angled differently every time I undo, make some changes to other parts of the face, and resmooth. I'm baffled. I've had problems with the files this model is in getting corrupted, I'm thinking it might have something to do with a bad material or something, so I'm not inclined to just ignore this glitch. user added image

Seems like everything does it when smoothed. Check out the line coming from the hair...

Is there a vertex on the end of that thing?

I've seen bugs like this in other 3D packages. My recommendation (if you can stomache it) is to export your models as dxf objects, start a new project and new scene file, import the models back in and start over. That way you have a new clean file to work with.

If you can't do that, and it's rendering correctly, you might be able to get away with doing nothing.

No, no vertex.

I'll probably export it, just for good measure... but it would suck to have to reassign materials to all of those faces. :-p I guess I'll just keep an eye on it for now. Thanks for the quick responses, guys.

I had something like this on one of the characters I was doing. Seems that some of the vertices were not merged properly, so check yours. It could also be a very nasty bug as if you rotate your perpective view the lines disappear.
