LOD/Culling Problems
If you get objects not being visible or showing bad LODs there are a couple of things you could try:
If you have nanite objects with masked materials and they are culled then you can lower Opacity Mask Clip Value for each material

UE Console Commands for non-nanite meshes:
1. foliage.MaxTrianglesToRender 200000000 (This is a heavy one and the default value is 100 million, so increase gradually)
2. r.ForceLOD 0
3. foliage.forceLOD 0
4. r.RayTracing.Geometry.InstancedStaticMeshes.Culling 0 (Maybe only useful in Path Tracer)
5. foliage.LODDistanceScale 5 (or other number, maybe only useful in Path Tracer)
Keep in mind that commands like this could affect performance.
If you experience culling in huge World Partitioning Scenes you have to use the converter in Dash, “Convert Instances to Foliage”. This will break the tool connection so you can’t adjust the scatter anymore with Dash, but you will be able to use the UE Foliage Painter tools to further adjust it.
Please let us know if you have any other useful tips here! There could be many different reasons why everything is not shown properly.
Another thing that is worth trying is:
6. r.RayTracing.Culling 0
7. Checking Ray Traced Shadows in the rendering settings
