class FLegacyConvexStructureDataLoader

Name	Remarks	Include Path
static void ExtractData ( const T_OLDCONTAINER& OldData, TArray< TArray< int32 > >& OldPlaneVertices, int32& OldNumVertices )	Extract ragged arrays of vertices per plane from the flattened array structure For use by LoadVariableSizePackedArrays to avoid code dupe based on index size	Chaos/ConvexFlattenedArrayStructureData.h
static void Load ( FArchive& Ar, TArray< TArray< int32 > >& OutPlaneVertices, int32& OutNumVertices )	Load data from an asset saved before we had a proper half-edge data structure.	Chaos/ConvexFlattenedArrayStructureData.h
static void LoadFixedSizeRaggedArrays ( FArchive& Ar, TArray< TArray< int32 > >& OutPlaneVertices, int32& OutNumVertices )	Orginal structure used 32bit indices regardless of max index, and they were store in ragged TArray> of vertex indices per plane.	Chaos/ConvexFlattenedArrayStructureData.h
static void LoadVariableSizePackedArrays ( FArchive& Ar, TArray< TArray< int32 > >& OutPlaneVertices, int32& OutNumVertices )	The second data structure packed the indices into flat arrays, and used an 8bit index if possible (and 32bit otherwise)	Chaos/ConvexFlattenedArrayStructureData.h
