- Add protection against async property accessed during async build and postload.
- Split PostLoad into 3 steps with the most part now being made async.
- Make Build/BatchBuild API async when the feature is activated.
- Add a new StaticMesh compilation manager. (This will be refactory later to reduce duplicated code with texture compiler).
- Skip RenderState creation for any static mesh component still being built so they only show up when ready.
- Fixed DistanceField and MeshCard computation that might trigger too soon if fixups are required to RenderData during PostLoad.
- Dynamic priorisation for building and updating static meshes nearest to the viewport.
- Implement different PIE modes, current default is to stall only for mesh that might affect nagivation/collision for players/bots.
- Add a new generic interface for assets being built (still a WIP).
- Add ability in FrontEnd filters to skip serialization of asset being async compiled and refresh when compilation finishes.
- Prevent auto-save while textures and static meshes are being built (same as shaders)
- Logic has been reordered in some Fortnite Building Component to avoid unnecessarily touching static mesh properties.
General Optimizations
- Use cached thumbnails until shaders/textures/static meshes are ready to improve performance and avoid rendering incomplete thumbnails.
DEBUGGING
- Can be forcibly enabled/disabled through command-line via -asyncstaticmeshcompilation=[off, on, paused]
- Can pause staticmesh compilation using Editor.AsyncStaticMeshCompilation = 2 or -asyncstaticmeshcompilation=paused
- Can manually resume a specified amount of paused compilation using Editor.AsyncStaticMeshCompilationResume [Num]
- Can forcibly wait on all compilation using Editor.AsyncStaticMeshCompilationFlushAll

Refactored FindField into FindUField and FindFProperty to avoid confusion caused by the fact that FindField<UField> will no longer return FProperties.
