I have been using UE5 for over a year now and I have been struggling to understand how to fix this issue.
So whenever I use screen space GI, the shadows become noisy and grainy, if I use other GI options, this issue disappears.
I also noticed that by increasing the project scalability the noise becomes less noticeable.
So I would like to know what is the feature/console command inside of Screen Space GI that is causing this.
Tried tweaking some values on the console that I thought it would ease the noise but nothing, heres some of the console commands I tried
r.FastVRam.ScreenSpaceShadowMask
r.FastVRam.ScreenSpaceAO
r.Shadow.Denoiser
Ps. The hair cards flickering its caused by something else, if someone knows what it is, please share the cause of it, I would appreciate it!
