struct FPCGMeshSamplerContext : public FPCGLoadObjectsFromPathContext

Extra context to store all the data that need to be kept between multiple executions (time slicing)

Type	Name	Description
TArray< TArray< UMaterialInterface * > >	AssetMaterialList
bool	bDataPrepared	Set to true if prepared data succeeded.
TArray< FGeometryScriptColorList >	Colors
TArray< TArray< UMaterialInterface * > >	ComponentMaterialList	Material Specific.
TArray< TObjectPtr< UDynamicMesh > >	DynamicMeshes	Dynamic meshes. Will be added to root.
TArray< FPCGMetadataAttribute< FSoftObjectPath > * >	MaterialAttributes
TArray< FPCGMetadataAttribute< int32 > * >	MaterialIdAttributes
TArray< FGeometryScriptVectorList >	Normals
TArray< UPCGPointData * >	OutPointData	Output point data.
TArray< FGeometryScriptVectorList >	Positions	Lists extracted from the meshes.
TArray< TFuture< bool > >	SamplingFutures	For Poisson sampling, we are starting futures that are not framebound Store the futures and synchronisation items in the context
TUniquePtr< FProgressCancel >	SamplingProgess
TArray< int32 >	StartingIndices	Starting indices for each different object to sample. If we have 3 meshes of 20 elements (like vertices) each, the array will be [0, 20, 40, 60].
std::atomic< bool >	StopSampling
TArray< FPCGMetadataAttribute< int32 > * >	TriangleIdAttributes
TArray< FGeometryScriptIndexList >	TriangleIds
TArray< FPCGMetadataAttribute< FVector2D > * >	UVAttributes	Optional attributes.
