Blender EXR Auto Pass Saver

Automatically link all render passes in Blender to a single Multi-Layer OpenEXR output.

EXR Auto Pass Saver is a Blender Python add-on that creates a Multi-Layer OpenEXR output node, collects all available render passes, and connects them automatically — saving time and avoiding manual node setup.
