Quote - before you decide the problem is the shader rather than your expectations, i'd suggest using the shader in an image where you actually duplicate an unaltered image.  pretty much everything in the media is altered, and our expectations have completely skewed accordingly.  it may be that with that lighting angle, her teeth would be shadowed by her lips to that point. 

metallic spandex is in development. i think the shaders are done, so i'm rendering stuff now.

I'm rendering atm as well - thank goodness for my lappie. It's the tulle - just chews through render cycles. Might have to bring this into P8 and see if it goes any faster.

The 3 images above were rendered with exactly the same lighting. My expectation was the last image... the first image was a detail of that first render.
Just so you have a bit more information to work with: lights... 3 point-lights, pos x=200 inches apart, y=150 inches, intensity 40%, ray-traced shadows. I think the pink lycra looks lovely on this outfit! Well Done! Can't wait for the metalic spandex... this is incredibly good material, cobaltDream!
