@joeral found this one:
When i attempt to load a lut into the Display LUT location on the deliverables page i get the following error.
“Object reference ot set to an instance of an object”.
If i leave this blank “None” and go into a project and assign the same lut as an output lut then return to this page it lets me load it.
Indeed this is a bug, probably related to some changes we made to make it easier to move LUTs and Stills from one system to another with a project. We’ll work on a fix. In the mean time, please use the workaround described above.
