I recently started to use Blackmagic's Fusion at home (budget reasons) and I'm liking it so far but, one of the most important features coming from Nuke, is obviously the ability to shuffle between all the AOVs of your multi channel EXRs. Unfortunately Fusion doesn't support this. It has something called booleans to separate RGB channels but not AOVs.
Chad Ashley pointed me to this third party script that splits a multi channel EXR in many different loaders with each one of your AOVs. Not as good as Nuke's shuffle but good enough!
