The fact that blender does not support multiple/custom passes output with .EXR files sucks if you want to use another application to do post production. The solution for this is to set a bunch of output nodes, and setting up them can be a real pain when you have to save a lot of passes.
So i have made this script that generates the directories for all output passes in the array list (line 24) and assing the new folder to the output node
here is the script:

ps: all the folders are created inside a “RENDER” folder.
ps2: the “Press to generate” button is located in the node panel ui in the left.
ps3: I´m a little bit noobish when talking about Blender + UI + Scripting, it would be cool to have the option select wich pass you want to output without having to change the script itself. Can anyone help me with that?
