Weird vertices on subsurf modifier I used edge loops, and then while cleaning up, I had to delete some vertices (dissolved) and then joined them again using faces. Now when i use subsurf modifier, when mesh looks weird. Fairly new and going through a tutorial to create a face model. If someone can point me in the right direction, will appreciate it.


Subsurf Off 





Subsurf On
The problem is due to faces with more than 4 vertices as the subsurf can only work with triangles (3 vertices) and quads (4 vertices).

Faces with more than 4 vertices are known as 'ngons' (basically 'polygon' with with the 'poly' replaced with 'n' to represent any number (greater than 4) - I can see two towards the top-centre of your image and it is those that are causing the issue.

The solution is to adjust the geometry to replace those faces with tri and quad faces. The easiest way to achieve this would be to simply cut one of the corners off to a tri, leaving a quad.
