Now here is where I run into a problem.

For the original V4.2 figure, the upper legs actually carry a "2 skinhip" material zone, and the skin texture applied in the original application on default V4.2  is "DD Torso" as you can see in the first image I posted above.

However, when I apply the "DD Torso" texture to the "Stockings1" material zone, I get large white patches on the legs, which aren't there when the "DD Torso" texture is applied to the original material zones of the legs.

The same thing happens if I include the hip area of V4.2 with the "Stockings1" (upper legs) material zone

able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
