I am new to 3d and blender. I am trying to do a Pink Floyd fan art thing where I have a dark, almost uniformly black scene with a glass pyramid and rays of light coming into and out of the pyramid. I have done some glass tests that I was satisfied with. (see thumbnail) My initial idea is to use the light saber tutorials from these forums to form the rays of light. Better ideas for the rays of light would also be very much appreciated.
How do I go about getting a black scene with enough light to reflect off the glass? If I place a black plane under the glass pyramid I cannot see the pyramid itself. Do I need an environment map or a light skydome or some other environment?
