Every now and then, check the rest of the head (I tend to use a different camera to do this). In the "Smooth Lined" mode you can paint facets to add with comparative abandon because it does not select "reverse wound" facets - so when you paint on the front of the ehad you do not select facets on the back of the head. However, it will still add right-wound factes that you can't see. For the example image I painted part of the lines at an angle which had the left ear directly "beneath" where I was painting. Although *I* couldn't see the ear, Poser selected all the facets which were "pointed" towards the camera. I need to de-select these with CTRL-click (or CTRL-Drag) and then check the pattern at the front (and add in any factes I inadvertently removed while cleaing up the ear, then check the back again...). Once I have the design correct, with all the facets I want but only the facets I want in the group, I'll move on to the next step.
