Split_EXR

I’d love to share a little tool I’ve been working on for handling EXRs.

As you know, splitting EXRs is something we all have to do from time to time — and it can eat up a lot of time. So I built a small tool, kind of like PSD layers, but for EXR. The idea is simple: you can decide which passes go into your main branch, and which ones stay on the side as utility passes.

Here’s how it works:

• Set your viewer to the EXR and select it

• Go to Tools → Split EXR

• If you want, hit Open Preview to quickly check the layers (works if your viewer is on the EXR)

• Drag the layers between Main (color) and Utility

• Hit OK — and you’re done ✅

This is just the first version, but I’m planning to add a few cool things later:
👉 an option to choose vertical or horizontal layouts for the node tree
👉 automatic light groups
👉 easier ways to organize passes

Installation: just copy the split_EXR file into your .nuke folder and add the lines from menu.py.
