Is there a way to get variance in albedo channel as well as in the bump and roughness?

Have a look; no clue if it works correctly for bump, fresnel scale and roughness.
No code error messages at least.
Just play around; consists of 3 textures.

If you want to test it with only one texture; just change the value in all shader channels from "NUM_TEXTURES = 3" to "NUM_TEXTURES = 1"... and so on and so forth.
Code for provided channels should work in similar channels for different shaders; depends on what vec or real is being used by it.

Maybe someday we could add shared parameters for the grid noise options... to get more control.

Btw. crappy textures by me, so don't worry.

It had to do with using the same code on roughness channel and not working

Take a look.
Code corrected in color, fresnel, roughness, bump and normal.

Yes, I checked afterwards, the thing is, it has no affect on the bump channel

From what I gathered it only apply an overall change of gamma, making it all bumpier, rougher, fresnel... but not take into accommodation the actual image, still thank you for the material.

Here's my test, it has a lot of pictures for randomizing either bump and roughness, but the randomize seems to only happening regarding the amount of roughness

Yeah, maybe someone who has got skills in ISL should take a look... ^^

xD Still you took it a level beyond, thank you very much!

After some tweaks I think I got it working!
