The landscape does not cast shadows

Hi @ChSt15,
Your problem is directly related to fix of my patch from the Epic GPU Lightmass which requires DX12 and SM6 enabled along with installing my backported patch
EpicGPULightMassPatch/README.md at main · jimshalo10/EpicGPULightMassPatch (github.com)

This was built to fix the problem
