This Application lets you batch several rendered EXRs into Photoshop, set cryptomattes into alpha channels and organize render passes in a folder structure.

You can batch this process for larger files during time away from your computer or on an external/remote machine, thus saving you time that otherwise will be wasted opening files and arranging them manually.

Technical Details

The EXR to PSB application runs on python using Pyside2 for the UI and the win32com (pywin32) module to access Photoshop and perform operations.

Reads the binary data on the cryptomatte exr to count the number of cryptomatte objects, Photoshop has a limit of 57 alpha channels which a warning message will pop up to let the user know.

Developed for EXRs rendered in Maya with Arnold render engine, render passes can be easily set to adjust for other render engine file naming conventions.
