    For linear exrs rendered from Unreal, what is the best color management workflow?

    I have been using William Faucher’s non-ACEs linear exr workflow

    In Unreal disable tone curve before render and then

    Color science > ACEScct

    ACES Input Transform > none

    ACES Output Transform > Rec.709

    And then right clicking clips > ACES Input Transform > Color Space Conversion > sRGB Linear

    Would there be any advantage or use for CST nodes instead?

    Hey Jim,

    Personally, I tend to use the CSTs when grading because, as a colourist, I like to have full control of the transform functions. That said, it requires a bit more understanding of the said transform functions, as well as a bit more time to set them up correctly. if you are interested in knowing more about the CST, let me know!

    one thing that I noticed in Faucher’s process is that he is setting the output to Rec709. You should set it to Rec709 Gamma 2.4 instead.

    Finally, I would probably recommend you use the ACES workflow, as that allows for more colour fidelity when moving from one software to the other. This last part, though, is not mandatory.
