How to create a totally black material? I am trying to create something that is TOTALLY black. I don't mean something like diffuse, or glossy, where things will reflect off it and lights will light it up.

I mean something that is totally black.

Is this possible to do?
Unless I am misunderstanding you. In cycles this is just a black diffuse shader.

The material doesn't reflect or anything if you don't add fresnel or gloss to it.
