Environment, backdrop etc.

[skratlat]

Hi All,

as a mr newcomer, I'm struggling to set background shader. Initially I thought that I have to set it on camera.environment, but that doesn't work. I don't have access to any 3D package (maya, max), I'm working using RealityServer, I examined sample scenes that seemed to have some background, and I couldn't find anything apart of camera.environment set to instance of mia_physicalsky.

Do I really need to use geometry instance to achieve "background color" effect?
