Hello @ tomaaron,

Thank you for your post.

Based on the log that you attached, Unreal Engine crashed with the following error:

Error: appError called: Fatal error: [File:D:\build++UE5\Sync\Engine\Source\Runtime\RHICore\Private\RHICoreShader.cpp] [Line: 37]
Shader requested a global uniform buffer of type ‘VirtualShadowMap’ at static slot ‘[Name: VirtualShadowMapUbSlot, Slot: 7]’, but it was null. The uniform buffer should be bound using RHICmdList.SetStaticUniformBuffers() or passed into an RDG pass using SHADER_PARAMETER_STRUCT_REF() or SHADER_PARAMETER_RDG_UNIFORM_BUFFER().

I don’t see any log messages that would indicate that the crash is related to InstaLOD. After a quick web search, it seems that this is an issue in Unreal Engine. You can find more information about this issue on the Epic Developer Community Forums:

Thanks!
