Fantastic; thanks Ono!!

... bump! :duckandcover:

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

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

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. :mrgreen: Just play around; consists of 3 textures. If you want to test it with only one texture;...

Well we have to change the code into vec2... then it should work in these channels; blend also f.e.
I am too dumb for maths, but I can take a look..

... to make it clear to me:
The problem disappeared with 4.2.18 and above?
I know that the sunsky-model has been „corrected“ with OpenCL, so the problem might have been situated there...

Thanks for pointing out and making it clear!

Fantastic!!!!!

Second wild guess: what color profile do you use in Photoshop(?)?
Is your monitor calibrated?
Color profile of monitor and photoshop should be the same.

Not if you take a closer look. Maybe in small and for studio, artificial lighting, but definitely not for natural lighting. YET.
You won’t ever get real-time caustics f.e.

Oh how nice!

Very nice fog in the second image? Is it Indigo or posted?

Yeah!

Yeah!!!!!
