SparseVolumeTexture.cpp

UStreamableSparseVolumeTexture::GetStreamedFrameProxyOrFallback() now directly returns the loaded scene proxy of the requested frame instead of going through the SVT streaming manager logic. This is more robust and fixes certain issues in editor builds.

SparseVolumeTextureData.cpp

Implemented multi-phase initialization for SparseVolumeTextures.

SparseVolumeTextureSceneProxy.cpp

Improved FSparseVolumeTextureRuntime::SetTileMappings() performance. Replaced unnecessary Read/WriteVoxel() calls with a single memcpy() call to copy entire rows of source data at once. Also used ParallelFor to copy tiles in parallel.

SparseVolumeTextureStreaming.cpp

All SparseVolumeTexture mips are now stored in the same resource/proxy, making binding and sampling different mip levels much easier. This version is still missing streaming at mip level granularity and has a minimum mip level size of 16x16x16 (no mip tails). Since the added logic started bloating SparseVolumeTexture.h/.cpp, FSparseVolumeRawSource (now renamed to FSparseVolumeTextureData), FSparseVolumeTextureRuntime and FSparseVolumeTextureProxy were moved into their own files. FSparseVolumeTextureData stores a potentially mipped (after cooking) 3D page table indexing into linear arrays of physical tile data. At runtime the physical tiles are rearranged/packed into 3D physical tile textures in FSparseVolumeTextureRuntime and the page table payload adjusted from indices to 3D tile coordinates. The SVTSample node now also takes an optional MipLevel parameter which enables sampling across mips (lerp).

SparseVolumeTextureUtility.cpp

Fixed VDB importer missing tile data on import. Implemented SVT tile deduplication by hashing and redirecting page table entries to identical tiles, potentially saving a good chunk of memory on suitable assets.
