Background image in RT

[tricky]

I'm trying to match the lighting of my 3D model to the lighting in a photo (I am creating a new building facade to an existing building). How do I make the background of RT show the background photo?

I have the photo in my env slot and it is visible in the vp background. Just not in RT. Obviously normal Vray rendering works just fine - I just thought that light maching would be a cool use for RT.

From the RT/GPU docs - perhaps it will help (if you are using RT/GPU)...if not let's look deeper...

Environment Mapping

Only the background texture from the Environment dialog is supported and used for background, GI, reflections and refractions. Only spherical, mirror ball and angular environment mapping types are supported.

This work fine in the CPU version of V-Ray RT.
