    Hi! I'm using HDRP in Unity 2021.3.

    Sometimes I get pixels that don't render correctly. The blue dots in the screen shot are the same color as the sky.

    Can anyone which HDRP graphics settings might be responsible for this?

    Thanks!

    Just a guess but try disabling SSGI then SSR and see if they still appear.

    I've used HDRP for a long time, since day 1 I think. And I have shipped 3 games with it and have not come across this issue. Not trying to say that it is not HDRP related though. Just saying that I've never seen it.

    From the looks of it, it looks very similar to faulty GPU or bad cable. I've had similar issues before that looked like those pixels with "about to die GPUs" or slightly lose cables.

    Unless u are using extreme exposures and getting NaN errors (you can enable NaN fix in the camera component) or have a lurking flare component with twisted values, it looks like hardware related. It can't be lighting related as Unity lighting doesn't have that kind of pixel precision :)

    Maybe double check GPU cables or try on another PC. Could be that.
