Camera Imager's "Custom LUT" option is not available in OCIO mode.
To use LUTs, you must convert them to OCIO LOOKs,
which can be selected in the OCIO Camera Imager tab:
How to convert LUTs to Looks:
For ACES config users
1) Drop your LUT files into the luts directory of the OCIO config
2) Add this code to the bottom of the config.ocio file:
Info:
- You can use almost any LUT file: .cube, .3dl, etc.
- The "process_space" should be the space your LUTs are for"
I created a separate folder and named it "looks".
But if you do this, you will need to change this config.ocio line:
to this:

- For regular Rec.709 LUTs, "process_space" is "Output - Rec.709"
- For ARRI LUTs, "process_space" is "Input - ARRI - V3 LogC (EI200) - Wide Gamut"
- etc.
