Anything ticked under Preserve? Might be either one of those 2, if not the problem's with the mesh.Thanks for the suggestions. It took me a while to wrap my head around it but in the end I was able to build the character from quads, with only 2 or 3 exceptions. I looked at the alien tutorial but the character seemed way to advance for me at this point. I'll do one or two more low-poly characters before moving on the aline.. Anyways.. I got my character finished.
I'm pretty happy with the result, ended up under 2000 tris. I don't plan to smooth him (subdiv proxy + crease tool), but I did just to test the geometry and everything works fine, everything but the mouth. Every other edge got rounded but the mouth keeps its original edges. Any idea why?
