[Openexr-user] EXR layer naming conventions

[Jim Hourihan]

Hi All, I was wondering how people are using EXR layers. Especially  
how the layers are being named and if there are any defacto standards  
out there.

For example:

        channels: R G B A Z diff.red diff.green diff.blue ...

Where the diff layer has slightly different channel naming convention  
than the "default" layer.  I assume that some of these things are a  
result of matching channel/layer names to shader parameters. A brief  
email conversation with Florian produced the idea that some sort of  
recommended best practices might established for layer naming, but  
I'm wondering if that's even feasible.

I'm also interested in whether people are using EXR to hold stereo  
pairs and if so how.

Thanks.
