graham wihlidal 74afe5e13b [Nanite-Skinning] Fun hack to temporarily "fix" broken cluster culling and VSM - Set the cluster bounds for skinned meshes equal to the skinned instance local bounds for clusters and also node hierarchy slices. ...

This satisfies the constraint that all clusters in a node hierarchy have bounds fully enclosed in the parent bounds (monotonic).

Note: We do not touch the bounding sphere in Bounds because that would break actual LOD decimation of the Nanite mesh. Instead we leave these in the offline computed ref-pose so that we get reasonable "small enough to draw" calculations driving the actual LOD. This is not a proper solution, as it hurts culling rate, and also causes VSM to touch far more pages than necessary. But it's decent in the short term during R&D on a proper calculation.

[Nanite-Skinning] Initial rasterizer support for linear blend skinning under a permutation to avoid affecting performance of rigid meshes. There are still quite a number of critical missing pieces, such as correct bounding volumes under deformation, and the tangent space basis is currently ref pose, leading to lighting/shading issues. Motion vectors are also not exported yet, so TAA has plenty of ghosting artifacts. All in good time...
