When I set this mesh to SetSmooth+SubSurf it shows a strange distortion. However it looks good with only 1- either SetSmooth or SubSurf.
See the gator’s head (above)
The head as SetSolid (above)
The head as SetSmooth looks OK (above)
The head as SubSurf 1 looks OK (above)
The head with BOTH SetSmooth and SubSurf looks pretty funky around the mouth area. What is the cause of this?
