I have been trying to get our lut out of nuke to work on DJV with no success. DJV wont read a .cube file or .3dl I found this thread http://forums.thefoundry.co.uk/phpBB2/viewtopic.php?t=2445&sid=cb85bbd002b8701a011448af18163073 that said DJV will read a png. file for a lut so I wrote out the lut using a vectorfield node in nuke and render it to png. While DJV did read in the png file the it just displayed a black screen Anyone got any ideas how to get DJV to load a Lut?
