OK, this DWA compression seems pretty awesome, Karl. Kudos! I wrote up a blog post complete with demo movie here: http://fnordware.blogspot.com/2014/08/dwa-compression-in-openexr-22.html How do you guys use it in your pipeline at DreamWorks? One thing I noticed is that it doesn't seem to apply lossy compression to anything other than RGB channels, is that right? Also, what happens if you send it 32-bit float instead of our standard 16-bit? Brendan
