This is an enum to say which target to reduce to for the fallback. It makes the default "Auto" which gives us more ability to change the default heuristic without needing to change uproperty defaults.
Along with this added r.Nanite.Builder.FallbackTriangleThreshold. Any mesh with source triangle count less than this threshold uses the source triangles directly for the fallback.

BoneInfluencesLimit can be set on each LOD of an asset. DefaultBoneInfluencesLimit is a per-platform global default that can be set from the project settings.
This allows you to, for example, enable Unlimited Bone Influences on a project while ensuring that meshes don't use more than 8 influences by default, even if they've been imported with more.

The threshold in LOD generation to check the quality of the LOD was to small.
It has been update to sqrt(3) i.e. the reduced mesh must stay in the bounding sphere.

The spikes seems to not happen any more with the new simplification algorithm.
Whatever, the bounding box of the simplified mesh is compared to the original mesh. If the new bounding box is larger, a message is output.

-Nanite-specific settings for tangent and degenerates are no longer also applied to the non-nanite mesh LODs on the same mesh.
-100% fallback meshes now have identical tangents to input mesh. Don't skip the tangent generation in StaticMeshBuilder for these meshes and don't recalculate tangents in Nanite builder.

Tangent generation now also respects the Nanite project setting, not just the per-mesh setting.

Add some CPU trace for interchange task, fbx translator, skeletalmesh factory.
Fix issues with UVs count crashing when there is no UVs layer.
Add generic pipeline asset to always cook in the plugin game.ini config file.
Make sure we use only half of the worker thread to avoid deadlock because there is no worker thread available.
