Hello SinnPhilipp,
I have tried this some hours ago by set it at 42 and it crashed the game. I just tried with 32 and it works great!
It is been a while I am have been looking for a solution, thank you for this answer.
In case, I also set r.Shadow.Virtual.ResolutionLodBiasDirectional to -4, it also increase the area of the virtual shadows.
I have heard about raytracing but did not know if it could help in this situation. If yes, I am curious to know more about it. Also, when I set ‘Cast Ray Traced Shadows’ to ‘Enabled’ on my directional Light, the shadows disappear. I don’t understand why.
