Hiyas! I really hope, you can help me out on this one. I'm tryin' for a few hours now to do the Dragon Head-Tutorial. It's really great, and I already learned an awful lot. :-) But I can't get on with it, because my Polygon Object f***s up. (Sorry for the language, but I'm quite freaked out already). It says, I've got "nonmanifold vertices". When I tell the Cleanup-Tool to highlight 'em, I get four or five vertices of a face, I just extruded, and then Merged. When I tell the tool to Clean the mess up, I can convert to Subdivs, but the area looks like a lot of small bubbles and not a closed surface. When I merge the vertices again, I get the error-message again. Please help me! Thank you
