In the above tutorial instead of using heavy 1MB .CUBE files, 26kb image files are used to generate the lut filter .
I was wondering if it was possible to use the same image in the LutPass ?
I tried using the method where the image is loaded on canvas then its written into the image key of a dataTexture . but the results seem way off. but works without errors.
is there something i’m missing here or is my entire approach wrong ?
i tried loading this image in https://threejsfundamentals.org/threejs/lessons/resources/images/identity-lut-s16.png (256x16)
and this is the result i got (its supposed to be the neutral LUT and should not have any effect)
