Thanks, Ironbear! Never woulda thought of that. This might sound sort of obvious, but it's yielded some awesome results for me: For a cool abstract background, use Nerd's backdrop prop or the RDNA Infinity Cove. In the materials editor, make object and ambient color solid black, highlight and reflective colors white. Apply a very simple reflection map, starfield, or some such uncomplicated image as the texture (or use none.) Use a more colorful or textured reflect map as "reflection map" (set to 90 - 100%.) Highlight: 90%. Trans sliders "off." Obviously this is using a "chrome" technique on the backdrop. With some clever planning and lucky experimentation, you can get some beautifully smooth abstract effects. The attached render shows this effect using two metallic reflection maps on the drop.
