If anyone wanted to have the option to output separate AOV with directories instead of multilayer EXR (Similar to how Redshift outputs AOV's). I have created a hda that will output passes separately.
Some studios preferred this structure so I made it just in case.
In this node, you'll just have to place it after the rendersettings, or else the separate aov rendersettings will be overwritten and won't output each file separately (which is also an issue with the cryptomatte node).
With my node just check on separate AOV, set your save location and file type, then just select the aov's you want. This is just a modification to the karmastandardvars LOP

Here is the GitHub link to the hda: link [github.com]
