Well, now I am getting a new error. Seems like this one is not sure to happen, more like 50-50.
Assertion failed: ResourceMap.Contains(Resource) [File:D:\build++UE5\Sync\Engine\Source\Runtime\RenderCore\Private\RenderGraphValidation.cpp] [Line: 790] Resource at 00000B58EC266200 registered with pass LightmapGBufferTile is not part of the graph and is likely a dangling pointer or garbage value.
