Maya mental ray gradient background attached to camera?

malcolm

Is it possible to hook something up similar to an image plane that has a gradient on it so the gradient always fits the background. Basically a screen space gradient for mental ray, the environment on the camera doesn't accept maps and image plans don't seem to render.

Why not just render an alpha channel and composite the gradient in?

Yep that's what I've been doing, would be nice if I could just through something in for test renders though.
