It was OpenGL. Changing to Skree (which I had never heard of) fixed it. Thank you very much. Clearly I don't know what I'm doing. I'm attempting to learn EZSkin2, but still don't understand it. It says Victoria 4 (whichever name I give it) is an unsupported figure, and the box of figures to check contains figures I don't use, or have never heard of.

It will take awhile, but my time is limited, my tech knowledge of a bygone era. 

Here's the material room advanced screen for "torso". Unable to get "abdomen". Looks very daunting. No idea what's happening in there. :-)
