Re: Rendering to multichannel EXR
FYI. It's much slower to render all channels / layers to the same EXR than to separate files. OpenEXR 2.0 can save files in a new, non-backwards compatible way which makes it as fast as separate files but I highly doubt Softimage / MR uses EXR 2.0. /Jens On Mon, Apr 21, 2014 at 2:00 AM, Siew Yi Liang soni...@gmail.com wrote: Hi Steve: Yep, that was an idea I had...it's a bit overkill for my little short animation test, though. :P Quite amazed that having never gone through MR in XSI for a while, this is still a missing feature from the mental ray integration considering the FX Tree...
