As much as I like the multichannel capabilities of nuke and exr. I prefer to 
shuffle out the channels I'll be using. There are scripts for splitting out all 
channels, search nukepedia. As long as you organise your nodes as you go, your 
script will be a lot easier to read for other artists and yourself.

An other benefit of splitting out is that you don't run the risk of forgetting 
to switch channel in the viewer. I know I've confused myself in past by simply 
viewing the wrong channel.

Cheers,
Elias
