Hi. Could you help me out with this shader? I'm struggling with it since months... ^^
TLDR: Do you know why this works on SDR but isn't on HDR? The original shader worked on both and only 3 lines of code have changed... I marked them at the end
more info: This is a vibrance shader that has 2 conditions. The first one is the srgb threshold float Thresh = 200.0/255.0; the 2nd one is the saturation of the pixel delta = smoothstep(0.8, 0.9, colorSat);
What I found out is that if the first number is higher than the 2nd one delta = smoothstep(0.3, 0.2, colorSat);, then you can see some changes but this isn't working as expected. This saturation condition is somehow broken.
By "isn't working" I mean that it visually doesn't change anything. The shader is working in the pipeline but there is no visible effect.

Thank you :)
The original shader, works on SDR and HDR
