I’m not even sure how to respond to the OP. A contest and it’s rules are up to the person(s) hosting the contest, what ever the rules may be… They are what they are, and selected for whatever reason. No need for rhyme or reason.
As far as the “only in DAZ Studio 4.5”... Sheer Greatness! is a DS4.5 (and above) only product. It’s cool that is works (partly) in LUX or Octane, but it still was created for DS4.5, and that is the only product that it is officially supported for.
Zev0 did the panty hose part of this product… My baby is the shader, so of course I’m more partial to that part of the product. I’ve done some ‘comparisons’ between DAZ Studio and LUX (using LuxRender) and the shader does not completely translate to LUX. (See render below) I know that in the contest you do not have to use my shader, but of course I want to see what’s done with it! Since it really only works completely as intended in DS4.5, then I feel that DS4.5 should be the only product used to create the renders for this contest.
The LUX render was a real quicky (but you can see the direction it’s going) I’m not saying it’s bad, but it’s not rendering the same as the DAZ render. My guess is that the Inner/Outer Blend is not being picked up by LUX.
