I thought the advantage of using OpenEXR was to save all my passes in one single file and be able to use that in PS or other image editing software, but when I click 'save All', an OpenEXR file is created for each pass (z depth, reflec, refra, id, etc.) So... what is so special about OpenEXR besides being 32 bit?
Also, can someone clarify for me which passes do I need to re create the beauty pass? Thanks!
