Authoring lookup textures for HDRP
Lookup textures (LUTs) are color cubes that HDRP can apply to produce a final color-graded image. HDRP takes the original image color as a vector and then uses that to address the lookup texture to get the graded value. LUTs for the High Definition Render Pipeline (HDRP) use a CUBE file.

The current guides cover the following software:
