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?

I just noticed that if I resave an exr pass out of imf_disp, it gets a lot smaller (5MB to 700KB). If I open that in PS, it says (RGB/32), so it should be the right bit depth? The original black exr pass files also show RGB/32 in PS.

EXR passes are really starting to annoy me. I've been trying to use render passes in every shot since January, and I've not got it to work once. I realized that Maya was rendering passes into separate files because I added a <Render_Pass> token in the file name, so it forced that. Now I have a 32-bit exr file with all the passes in the same file.

Now my main problem is where I've got stuck at every time. I can't get the passes to look like the MasterBeauty. Using the proEXR plugin which comes with AE, I created a comp from the passes. It displays the MasterBeauty (or RGBA) correctly (first image), but the passes it didn't gamma correct, so I had to that manually. When I add or linear dodge the passes together, it looks like crap. And it doesn't seem to be respecting the mia_bokeh that I rendered.
