openexr bug
Closed, ResolvedPublic


System Information
win7 64bit, GTX650ti

Blender Version
Broken: 2.75a
Worked: 2.74

Short description of error
I used file output node set with openexr file type to output render layers and render passes . When I wanted to use these openexr file to composite, I found the image input node only showed one render layer.

Exact steps for others to reproduce the error
I had create a file named "bug", you can use this one to create a openexr file. I also created a file named "bug_1" with openexr file.

1, open the bug_1 file, then use view node to check each output node of the image node. Only one render layer can show up and work. If open the bug_1 file with 2.74, every output node of the image node works.

I just test with 2.75-5668fc0, and the bug still exists.

Cannot reproduce here. Please attach here also the .exr file.

Oh, OK, sorry, it’s me who did not understood correctly the issue…

Can confirm something is wrong here, either on writing or reading side, will check.

Caused by rB479b6696, which removed iuser->pass index, leading to only select passes based on their view and type. This may work with pure-render result, but certainly not with random composite OpenEXR images. Thinks you need to re-introduce pass index here… @Sergey Sharybin (sergey) may also have some ideas?

Setting to high because this should really be fixed before 2.76 imho.

*sigh* yes I think pass index will have to be back
