Hi Doug,
I don’t deny that at all, I’m just saying that I could not get that to work in Nuke which is one of the largest OCIO app by user base. Does it work with Maya?
If it is optional behaviour, we are all good I guess, if not, this is an important problem. Given Scott and I reactions, it is not clear whether it is optional or required. My worry with handling extra channels is that if you were to process an image with two different applications, one processing the alpha and one passing it untouched, you would get two radically different images. It is a recipe for a ton of late nights debugging which we will surely agree is not a good thing, we are getting old
