Ok, I've been trying to get materials to reflect the background in Poser 11. I can't for my life get it to work. I set up the material with black Diffuse color, a Diffuse value of 0. I then add a raytracing reflective node with black color to the Reflection color. Reflection value is 1.

The object is now reflecting other objects in the scene, so far so good.

I have a diffuse IBL light with a HDR image. Which seems to work fine. It's not causing the reflective objects in the scene reflect the HDR image though. I then added the same HDR image to the BG Picture node in the Background settings. I attached that node to Color on the root Bakcground node. I even attached the BG Picture to BG Color. No background reflections.

I simply can't get the objects to reflect the background. What am I doing wrong? I suppose I could make a sphere with the HDR image as a texture around the scene but that seems like a poor man's workaround.
