What does it do:
Automatically breaks all of the light AOV layers out from your image into shuffle nodes and merges them back together correctly to preserve correct intensity and hue.
This allows you to control the effects of each light's intensity, hue et cetera indivudually without the need for re-rendering.
This tool will pair well with Auto-light AOV setup (Mtoa) to automate setting up the AOV's for you at rendertime.
Currently supports EXR renders from Arnold Renderer with more options on the way.
How to use it:
Select the read node that you want to break out layers for.
Open the "Yokai_Tools" menu at the top of your screen.
Click "Shuffle Out Lights".
Copy the contents of the provide ".nuke" folder to your local ".nuke" directory.
If you already have a "menu.py", simply append the contents of the provided one to your own.
