Having researched this quite a bit, my conclusion is: tl;dr - try Amplify Colour's implementation
According to Thomas Hourdel, unity's postprocessing lead, post stack v2 LUT is LDR only, and there are no known 3d log LUTs required for HDR available for sale: https://github.com/Unity-Technologies/PostProcessing/issues/507
I don't think anyone would have the time to do this: https://github.com/Unity-Technologies/PostProcessing/wiki/(v2)-External-LUT-authoring
see other attempts at using strip LUTs and converting 3d cube LUTs for use in v2: https://github.com/Philipp-Seifried/Unity-PostProV2-User-LUT-And-Z-Grading https://forum.unity.com/threads/post-process-volume-color-grading-3d-lut-cube-format-incorrect-color-display.628828/
for now, I'll restrict the LUT option to LDR only since it doesn't do anything with HDR colour grading enabled.
I know it's good but to implement external LUT we need more examples people to follow.
That's not what I said at all. I'm saying we will NOT provide support for external LUT, not the one provided by unity PPv2, it's not worth it.
closing as 0.2.0 exposed builtin LUT and support for external 3D log LUT it's not worth the investment.
As @ore- stated in #40, IBL needs to cover every single feature ILLUSION provided since we're taking another step further from ILLUSION's nest.

contains all the LUT information that post processing uses.
