Subdivision Surface mesh weird vertex behaviour I'm modeling a character and I've noticed some weird vextex behaviour that is deforming the mesh with the subdivision surface on it.




The vertex causing this deformity seems to bem "stacked" on the mesh, I tried to remove them and remake the part of the mesh but when I do this the vextex next the removed part keep the same behaviour, so I just pull the problem ahead...

You have a normal issue, you need to select all in Edit mode and press shiftN to recalculate. Also you'll have to disable the Subsurf Clipping option, select all the boarder vertices, move them a bit on the X axis to create a gap, then reactivate Clipping and move back the vertices so that it sticks correctly.
