Have any free tool or script special for it? :unsure:
I mean custom parameters - dimensions, palette(?), etc. Wanna to play with this shader.

With my LUT generator shader I can generate you any LUT dimension, also uneven ones (where the X dimension isn't Y^2 like it is with 256x16 etc). :dry:

I have not used Marty McFly LUT generator.
But here's a shader that can generate any-size LUT. Handy to bake some ReShade effects into one texture:
github.com/Fubaxiusz/fubax-shaders/blob/.../Shaders/LUTTools.fx
there are 2 techniques, "DisplayLUT" and "ApplyLUT", you would be interested in DisplayLUT. It will display generated neutral LUT in left top corner, you can adjust size (it represents box dimensions and number of boxes). Then take a screenshot and crop image to LUT size.

So it not very clear and direct method.
Maybe anyone known about Marty McFly LUT generator?, can't pm him, I do not see this option on forum.

Then use this script to generate texture github.com/Fubaxiusz/shadron-shaders/blo...eutral%20LUT.shadron
But you have to have Shadron www.arteryengine.com/shadron/
To save PNG just drag the LUT image onto desktop.

But I see the screenshot method more convenient, since you already have the reference image in the background to visualize your tweaks, and still you have to open and edit LUT in some graphics software like photoshop or Gimp to make it do anything.
