Just some days ago I found a question in the facebook Logik group about how to apply a preview look LUT in flame when working in ACES. I had to do this already sometimes, so I could help out amongst others, but for sure I will forget about it in the next weeks and won’t be able to find it when I need it again. So I put together the working steps that are needed to do the same in Nuke and pointed out some obvious limitations with 3D-LUTs in ACES.
