So I am making a logo and nightclubs is the theme with burgundy/black/white/gray colors. I am getting the hang of making a chrome-like material, but I was wondering how I would make a sweet logo without a background? Or how do I make objects not appear in the render, but still use them for reflections?
If no background means transparent background then you need to lose the sky layer (in Blender Internal) or in Cycles turn on transparency (in the film section) As for reflecting things not in the image, I usually add an HDR image to a plane then move it out of the camera view.
