When I enable the vignette, I can see these color gradients. I tried enabling dithering, but it does not help. Might there be some way to solve it?

Vignette effect is causing a color banding artifacts
Hi, this issue is nicely visible in a fog.
When I enable the vignette, I can see these color gradients. I tried enabling dithering, but it does not help. Might there be some way to solve it?

Re: Vignette effect is causing a color banding artifacts
Other than tweaking intensity and smoothness, there's not much to do here. Remember, the PPv2 stack isn't something by DFU, we're just providing toggles and sliders to Unity's own postprocessing solution.
Below are the effects available in PPv2, note dither isn't listed for any of the render pipelines.
https://docs.unity3d.com/2019.4/Documen ... d-location
The dither toggle in DFU is for the hard-coded "magic dither" at the end of Unity's Uber.shader and FinalPass.shader. I originally just disabled this, then later added a toggle.

This step really just creates noise imo, and I agree with one of your earlier comments that it should be removed or replaced with a custom dither postprocess shader. If anyone knows a good PPv2-compatible dither postprocess shader for Unity with a free license, I'll look at including it in a future release.
