Thanks JM I found that recently/independently and I'll be including it in an upcoming post.
The LUT tends to "like" (i.e., produce nicer results) erring on the side of under-exposure, maybe try pull-developing your CDNG within -1 stop with the LUT applied, see if that helps?
Thanks a lot! Most of the words (and material in general) come from Hunter so I take no credit for that but I was happy to share this. Hunter's LUT & Tut helped me a lot as well!
I'm working on a 5D3 ML RAW walkthrough now and the workflow is quirky but so far for me, solid as a rock.
It should show up in Resolve regardless of what camera you're shooting on, try restarting Resolve. If that doesn't work double check your steps and make sure it's a .cube
Like I said, you need to play it before you judge.
