unity – Terrain shadows not rendered to additional camera with Unity3D URP

I’m running into problems with a project using several cameras rendering to different monitors.
The first Camera (a VR camera) renders the foliage and the terrain correctly.
However, in the second camera view, I see the objects are receiving light, but are not casting shadows on the terrain.

  • Culling mask of both Cameras is set to “Everything”
  • Trees and other objects have shadow casting enabled (and render correctly to the main Camera)
  • I tried changing the shadow distance, without any result
  • I tried different terrain light modes, which didn’t help
  • I tried using the same renderer for both cameras, and a different renderer for each camera, without success
  • I tried putting all the cameras and lights on the same object layer, without any success

Any hint about how to solve this issue?
