class FMeshDescriptionToDynamicMesh

Convert FMeshDescription to FDynamicMesh3

Type	Name	Description
bool	bCalculateMaps	Should we calculate conversion index maps
bool	bDisableAttributes	Ignore all mesh attributes (e.g. UV/Normal layers, color layer, material groups)
bool	bEnableOutputGroups	Should we initialize triangle groups on output mesh
bool	bPrintDebugMessages	If true, will print some possibly-helpful debugging spew to output log
bool	bTransformVertexColorsLinearToSRGB	Should Vertex Colors of MeshDescription be transformed from Linear to SRGB
bool	bVIDsFromNonManifoldMeshDescriptionAttr	If the source MeshDescription is non-manifold, store mesh vertex id as a vertex attribute on the result mesh This data can be accessed using FNonManifoldMappingSupport ( see NonManifoldMappingSupport.h)
EPrimaryGroupMode	GroupMode	Which mode to use to create groups on output mesh. Ignored if bEnableOutputGroups = false.
TArray< FTriangleID >	TriIDMap	Map from DynamicMesh triangle ID to MeshDescription FTriangleID
TArray< FVertexID >	VertIDMap	Map from DynamicMesh vertex Id to MeshDecription FVertexID.

Type	Name	Description
void	ApplyVertexColorTransform ( FVector4f& Color )	Applies an optional Linear-to-sRGB color transform on the input.
void	Convert ( const FMeshDescription* MeshIn, FDynamicMesh3& MeshOut, bool bCopyTangents )	Default conversion of MeshDescription to DynamicMesh
void	CopyTangents ( const FMeshDescription* SourceMesh, const FDynamicMesh3* TargetMesh, UE::Geometry::TMeshTangents< float >* TangentsOut )	Copy tangents from MeshDescription to a FMeshTangents instance.
void	CopyTangents ( const FMeshDescription* SourceMesh, const FDynamicMesh3* TargetMesh, UE::Geometry::TMeshTangents< double >* TangentsOut )	Copy tangents from MeshDescription to a FMeshTangents instance.

	Type	Name	Description
	EPrimaryGroupMode	Various modes can be used to create output triangle groups
