When I render .tif files with mental ray, the background is missing. I have a scene that is lit with a HDRI file. If I open the .tif files with Mayas included .map file viewer (imf_disp.EXE) the sky shows up, as does the alpha channel. But when I import the file into after effects or photoshop, it only shows the foreground object matted against a transparent background. Also the .iff z-depth files that maya turns out can't be read or opened in photoshop (I have the .iff plugin) but can be viewed in the imf_disp.EXE program. Any ideas on what is wrong and how to change it?
I will give 5 billion dollars in gold to the person that helps me solve this problem.
