Hello there @olegwer1!

Checking through the community for similar scenarios, there are a few parameter changes to test around. From your light’s source details’ panel, adjust the following:

  • Shadow Map Channel: set to 0

  • Shadow Map Resolution Scale: switch between 2.0 to 4.0

  • Virtual Shadow Map Bias: go from 0.01 to 0.1

  • Normal Bias: switch between 0.2 to 0.3

  • Dynamic Shadow Distance Movable Light: increase to 20000

  • Also, it is always useful to update UE to the latest, stable version (these days, either 5.5.4 or 5.6.0 will do the trick), as well as setting your video drivers to the developer version.

  • Finally, check the thread and documentation below for more methods to test:
