Hi guys. Where can I find that material in max scanline that I can assign like to a simple plane where the plane blends with the background color but still able to receive shadows (like the image below from 3point) and how to set it up. In maya I know there's a default background shader in hypershade, and that's what l'm looking for within max. Thanks guys.

It's called the Matte/Shadow material, I think the settings were pretty self-explanatory but haven't used it in ages :P
