As it stands, LUTs in UE4 are strictly an srgb color space modification, and pretty wonky to deal with as image files. Colorists using truelight/resolve, etc are used to working with text-based lut files that are easily shared and exported/imported. Often, these are not just 1D luts, but 3D luts or cube files. They are commonplace in professional workflows and are global operations to simply reach a base level of “look” to where and artist can blend it with their own tweaks.
Given the excellent work done in 4.15 to support ACES color workflow, and much improved tonemapping and grading controls…
Would it be possible for unreal to import a cube instead of the srgb image file so that our colorists can grade a scene quickly and easily using their preferred tools?
It’s clear Epic has been giving the color workflow some serious consideration. Have there been any thoughts on your side regarding this?
Thanks for any info!
