Sun and Sky, mia_exposure_photographic and background image
I am a bit stumped. I have a simple scene lit with MR sun and sky. The default setup uses a mia_exposure_simple node connected to the lens shader of the cameras as well as the mia_physicalsky node. Specifying a background image on the physicalsky node (mib_lookup_spherical + mentalray_texture) works like a charm.
The moment I swap out the mia_exposure_simple node with a mia_exposure_photographic, the scene objects renders ok but the background is black. What am I missing?
The RGB unit conversion is set to 0.318

Somewhere around part 11 i go over using a sphere environment with the correct reflections, the exposure photographic use background wont show in reflections, so it's not the best way to do it.
