Light Path Expression (LPE) Script and UI
Setting up LPE per shot is a slow and tedious process.
Create a User Interface that will easily create AOV for each light group.
How To Use
In your light's shape, define a custom name to create a light group. (Arnold > Visibility > AOV Light Group)
Next, run the script LPE Script. The script should pop up on the right side.
Select which AOVs are needed in the shot.
The script will create the proper AOVs for each light group found in the scene.
Render and import files into Nuke. I used an AOV Splitter (
) to quickly organize and merge all the shuffles together.
