I’m experiencing an issue with foliage flickering and haven’t been able to find a solution.  
Is there any way to fix or reduce the foliage flickering?

i had this issue, i gues u are using Ray Tracing right? if not. Look it up. and Enable Ray Tracing insted of using project settings.

Then i use this in my config file. Just copy this and paste it in your default engine

```auto
[/Script/Engine.RendererSettings]
r.RayTracing.Shadows.SamplesPerPixel=8
r.Nanite.LOD.AutoLODPixelError=8.0
r.TSR.Shimmer.Enable=0

```

or u can cpy this r.RayTracing.Shadows.SamplesPerPixel=8 and paste it in your “cmd” console command in the program see if it works first.

dear regards

If the problem is still relevant, try what’s shown in this video, it seems to work fine.
