The manual here

describes how to get color grading LUT by manually adjusting image in the Photoshop and visually controlling how it looks.

I’ve got a pair of images of a photographic color grading palette (like one of these: 4 Things You’ll Need to Become a Film Colorist).
One was captured by a real photo camera, and another one comes from the SceneCaptureComponent2D.

I’ve got the PDF file with that palette, and to get the latter image I’ve put it on a wall texture inside a UE level.

Is there any method to automatically create LUT?

My main issue is the color interpolation. Physical palettes contain about 20-50 colors, but the LUT includes 16x16x16 = 4096 colors.

poke here, any solution yet on how to get a LUT or create a list of color as a palette from a texture ?

Yes. I have ended up with the neural style transfer. Sorry that I can’t describe my solution in details.
