I have loaded the Rainbow Light Bodystockings(G8F), and while working in either Texture Shaded mode or NVIDIA iray mode, there is no poke through, but when I render the scene, I get poke-through. Of course I have adjusted the stockings, and although that does eliminate the poke-through, it also looses the fit to the legs, which looks bad. I'll also add that the leg is not bent to any extremes, and there are no exaggerated body morphs being added to the G8F figure.

Is there any displacement active on the hosiery or the figure?

It does show that there are multiple displacement maps for my figure, but not for the stockings. How does this affect the rendering?

As I recall the default Iray preview does not show displacement, so if it is moving the skin out that will not show until the final render. You could use a weight-mapped dForm or Push Modifier to make targeted fixes to the affected areas, or you could try removing the displacement and seeing if the result is acceptable.

I've run across similar problems at times, next time I will know to check out those displacement maps. Thanks guys.
