I rendered out openEXR files with passes associated. I get MasterBeauty and also refl refr diff etc. There doesn't seem to be any passes within the MasterBeauty itself, I can't remember how to put those all in the same file, but that's a separate issue (or maybe not).

When I open the exr pass files in imf_disp, they look fine (after correcting the gamma), but when I open them in AE or PS, they are totally black. The MasterBeauty file works fine in imf_disp and PS and AE. The MasterBeauty files are a little less than 3 times the size of the pass files. I wonder if they are the wrong bit-depth? The kicker is that if I open a pass file in imf_disp and then re-save it as an exr, it looks fine in PS. So Maya is not saving out the pass files properly?
