Re: [Openexr-devel] Multilayer convention

[Larry Gritz]

That sounds relatively standard, from what I've seen.

I'd like to think that with the release of OpenEXR 2.0, that we can phase out 
the practice of writing a "huge pile of channels" and hope the application 
sorts it out with naming conventions, and instead actually use the new 
multi-part feature to have a separate part for each pass/layer and a simple 3-4 
channel obviously named set of channels within each part.
