276d09f6df Remove all simple usage of REN_ForceNoResetLoaders from the codebase since the flag has been deprecated and currently does nothing. Simple in this case is direct use of the flag with no conditional logic. More complex uses were removed in another change.

a2b5613488 Slate: Deprecate SListView::ItemHeight and STreeViewItemHeight. ItemHeight and ItemWidth are only used when the panel is is as a tile or both value are assigned. With TreeView and ListView, you can't assigned both. The function are protected, a subclass of those could but it's up to them to expose the ItemHeight and ItemWidth. This behavior changed was introduced with CL 7634094.

05f8050519 Implemented support for SVT per-frame transforms. Transforms are read from from the source vdb files and are required to be identical for all grids in the same frame. The SVT viewer now implements support for applying these per-frame transforms. It does so by applying the the inverse per-frame transform when transforming from (translated )world space to local unit (and eventually UV-) space. 
Fixed SVT viewer breaking at LWC distances. It now uses translated world space instead.

ebff9cc9ca Fix for jittering SparseVolumeTexture frames when importing a sequence with different translations in the transforms of all the input files/frames. A popular third party tool for baking volumetrics unfortunately always creates such sequences. The UnrealEngine .vdb importer assumes that all frames of a sequence share the same transform and effectively ignores that transform. This fix detects changes in the translation and bakes the translation into the created SVT, eliminating the jittering.

19a4bedcf8 Fix for SparseVolumeTexture .vdb importer creating broken assets when importing .vdb sequences with this pattern: FILENAME.NUMBER.vdb. When importing a sequence, the importer creates an animated SVT and uses the filename with the number stripped at the end as asset/package name. With files using this pattern, we end up with a dot at the end of the asset/package name, which violates UE naming rules and makes the asset completely unusable without any proper warnings or error messages. The fix now also strips the dot (and other invalid chars).

a7483744c5 Fixed SparseVolumeTextureSamplePageTable() and SparseVolumeTextureLoadPageTable() sometimes loading from the page table at incorrect coordinates when the page table is using a page table offset. Fixed incorrect page table offset in SVT sequences causing parts of the volume to appear cut off at higher mip levels. Fixed empty vdb frames during import causing massive VolumeResolution values in the resulting SVT. Fixed StreamingManager triggering an assert when all voxels of a higher mip level have been stripped away due to occupancy bitmask based compression. It seems that higher mip levels can sometimes be empty despite lower mip levels having valid data. I suspect that this is due to precision issues when averaging 8 small float values and then quantizing them during the mip mapping. 
Removed unused lambda in SVT factory.

75da662566 Implemented automatic asset renaming when importing .vdb sequences as an animated SparseVolumeTexture. The resulting asset name will no longer have the number postfix of the original file used to import the entire sequence.

838de94380 New streaming system for SparseVolumeTextures. It is based on the Nanite FStreamingManager design and supports streaming both from disk and from DDC. This first version uses a single logical tile data texture for all frames of a single UStreamableSparseVolumeTexture and starts streaming out tiles of older mip levels once it runs out of space. The highest mip level (lowest resolution) is always resident in the tile data texture, so there is always something available for rendering. Each frame's page table texture is currently always fully resident. There is now also a buffer storing the lowest resident mip level index for each frame. 
In a future version, additional logical tile data textures may be allocated to handle cases where more mip levels are being requested than can physically fit into a single texture. In addition, page table textures should also be resized so that streamed out frames take up less GPU memory. It might also be necessary to implement a blocking streaming option for MRQ and similar use cases. This feature probably depends on being able to spill to additional physical page table textures.

Also moved all of the SVT runtime classes into a shared namespace (UE::SVT), which is why this CL ended up touching almost all SVT related files.

fedfdecf2f Implemented an optimized path for creating a SparseVolumeTexture from a dense source volume. Also did a little bit of renaming of some of the involved functions/interfaces. Removed unorm-remapping option when importing a .vdb file. The usefulness of this feature is debatable and it doesn't work properly on .vdb sequences.
