Hi meetHG.
I'm not doing much of anything now.
Maybe only one or two months before this forum gets taken down by Ivo.

Glad you are still experimenting.
As you have done the most playing around with noise added to skins in the past, you know more about it than me.
I see using different intensities of noise peaks(white), and dips(black), along with a grey level can get different effects like splatter, salt n pepper look.
For myself, I tried to get that smooth noisy look of the Win 10 "Personalize" window but just can't get it smooth enough.
I know they boost the saturation color of the desktop background just behind, have different blur radius,
but it must be that "Exclusion blend" that makes the noise look smoother than what I can achieve.
Maybe not possible in CSM.
By modifying your noise bitmap a little, I got a little closer to the look I want, only good for certain situations though.
That's interesting that you got the noise to show up as RGB glass color layer.
Bye MHG.
