How to Fix Weird Crease in Character Model I've been working on this character for many hours, but just noticed there's a weird crease down her back. I've subdivided far too much to be able to just grab the edges and shrink it, does anyone know how I would fix this? I'm very new to blender, but I tried sculpting, and I can't really get rid of it without wrecking the surroundings.
As you can see in the picture, there's also some weirdness on the upper back and the butt I'd like to fix as well, but then again the character will not be naked so the butt's a nonfactor haha.
Some vertices of your mesh are going over the Y axis. Just a bit, but enough to cause a crease.


Select your whole edge
Scale it to 0 along the X axis (so it's flat)
Move it precisely to the Y axis.


(This is the fast solution, you can of course move the vertices one by one.)
