Description
We've added an option to the JRVR renderer to calibrate HDR output with a 3DLUT. .cube and madVR .3dlut are both supported.
Instructions
It works as simple as SDR 3DLUTs before. Just point JRVR at the file with a new separate 3DLUT option in the JRVR -> Output -> Calibration settings.
Calibrating with a 3DLUT should be done with help of calibration hardware, eg. a colorimeter, and calibration software - a free option is DisplayCAL.
HDR 3DLUTs should be designed for PQ BT.2020 in/out, and either be in .cube format or madVR .3dlut format
