Hi, I'm making my first attempt at modelling a human in Maya using box modelling. But I must have done something wrong because my model's gone haywire. It started with triangle appearing where there had been quads, then portions of my topolgy began morphing as I extruded added loops etc, and now large holes have begun to appear. I used fill hole, but for every hole I fill two or three larger one appear somewhere else on the model. What did I do wrong and will I have to start again? I'd appreciate any advice.
