Rendering metal textured objects with transparent background?

When you apply one of those metal (or glass) materials which are included in Cheetah3D v5 to a standalone object, it renders pretty much to a black surface. After searching the forum someone posted a trick where you would simply place the object concerned into a big white ball, and voila - now the surface eventually looks like metal (or glass).

The problem I have with this approach: I need to render the metal object standalone to a transparent background - and I haven't figured out how to do it.

Any ideas?

I'm not completely sure about what you are after here, but I think you might just want to put something interesting in the scene for the metal to reflect. Try lighting with the "entrance pano" HDRI that came with Cheetah or the famous "kitchen.hdr" that you can find all over the web, you should get some interesting reflections. Otherwise, try a large plane or half of a large cylinder behind the camera with a photo applied to a solid colored material. The transparent background shouldn't matter.

Ok, I somehow must have missed the HDRI thing - that looks promising indeed. Thanks!
