One other question came to mind - in the pre-render of this image - the bustier has reflections and highlights - however, the render itself - comes out flat or matte black. Some materials/colors/textures that I use, no matter how I tweak the dials and settings - do not seem to respond in regards to reflective properties, bumps, etc. Is there something that I am unaware of, that does not appear in the manual in regards to reflective surfaces? Hope you all had a happy new year.
