Rendering on a black background (=no background)

[gsfcreator]

Hi there, Otoy folks! this is a very simple thing that I've figured out a few years back and simply forgot. I wish to render on a pitch-black background, instead of the normal gray background I get when rendering a scene with octane for poser. I can't recall how to do this simple thing and it drives me nuts. something with tweaking the environment within octane pluging?
