Thanks for the info @BRS_GerDAngelo
I’ve profiled my display and have a 3D LUT, tested in Blackmagic Fusion.
Applying the LUT in UE post processing sounds doable. I imagine it would need to happen after the tonemapper, in 8bit land, so I’d lose some color depth, right?
If I’d rather use OCIO, do you know if there’s a way to embed my calibration LUT into that workflow?
I thought I might be able to embed the LUT into my OCIO profile, but I suppose I’d need to merge it with (for example) the sRGB - Display - ACES 1.0 - SDR Video to have it tonemapped?
I also thought about getting a Decklink or something to use as a LUT box, and it seems I may be able to output to that using a native plugin, but I’d be sad to lose the UI real estate.
