Backplate in c4d (Material with no light interaction)

Hey folks,
I'm working on a winter-illustration and created in the first step a matte painting.
At the moment I'm modeling the snow-environment in the foreground and just want to render the matte paining, that I put on a simple plane.
Doing this by putting the image on the plane via a material, the plain get's affected by the lights in the scenery, what I don#t want.

Tried to use the texture environment but I don't have a sphere, I need the texture on a specified plane. Any chance to get there?
I'm searching something that works like the background image in cinema.

The scene looks like that:

What I do in these cases is to use the back plate image inside an environment object and set it to background only... them... since is a normal image and not panoramic view... I would transform this image projection, rotation and scale to fit the composition as needed. That the only way I know to achieve what you are saying. Alternatively you can render with alpha channel ON and fit and adjust your background in Photoshop... I ve done both ways.
Cheers!
