- Cook side extra low lod coarse mesh will be created at 1/8th of the original coarse mesh if mesh streaming or editor data is available for the platform
- Nanite static meshes with streamable LODs are registered to a Nanite::CoarseMeshStreamingManager which will handle the stream in/out requests for these assets in fixed memory budget (memory budget is part of the total mesh streaming budget)
- Nanite proxy needs to handle different raytracing proxy LOD indices now for dynamic and cached indices
- What to stream is driven by what's used in the TLAS build - each deferred render pass all used streamable meshes are collected and forwarded to the CoarseMeshStreamingManager
- CoarseMeshStreamingManager is updated after all views are rendered and will make stream in/out requests depending on the TLAS usage
- When LODs of UStaticMeshes renderdata is loaded or unloaded then a rebuild of the cached render data is requested to make sure the correct LOD & RT BLAS is used (to do this the UStaticMeshComponent are registered to the UStaticMesh so a request for rebuild can be made for all the proxies on the scene)
