All over this scenes, shadows pop in and out in front of the camera at short distances (pay attention to the yellow building and to the building at the left):

I have done everything listed in this topic:

Anyhow, I’m not sure if this is a bug or if I need to change the way my lighting is being handled in the scene. When the camera distance (being driven by the SpringArm in the Blueprint) exceeds about 6500+ units all of the cast shadows seem to completely disappear or are not being rendered or registered. However, by just lower…

```auto
r.Shadow.FadeResolution
r.Shadow.MinResolution
r.Shadow.TexelsPerPixel
r.Shadow.RadiusThreshold

```

I also tried increasing Dynamic Shadow distance, but no effect.

Hello @AlfredBaudisch !

mmm what about:

r.ForceLODShadow 0  
r.ForceLOD 0  
r.ScreenPercentage 150

Hey Alberto, can you explain that ScreenPercentage has to do with fixing LOD shadows? I know that it downsizes from higher res into the defined resolution but does that fix moire or something?

It’s more resolution, as more resolution more quality, test it you will be not disappointed!
