Name	Remarks	Include Path
bool Init ( const FManagedArrayCollection& Collection, const FToMeshOptions& Options )	Convert all meshes in the given collection to dynamic meshes.	GeometryCollectionToDynamicMesh.h
bool InitFromTransformSelection ( const FManagedArrayCollection& Collection, TConstArrayView< int32 > TransformIndices, const FToMeshOptions& Options )	Convert the meshes in the collection at the given transforms to dynamic meshes.	GeometryCollectionToDynamicMesh.h
bool UpdateGeometryCollection ( FGeometryCollection& Collection, const FToCollectionOptions& Options ) const	Update a geometry collection with the current meshes array Note this updates a Geometry Collection rather than the more general FManagedArrayCollection because some of the updating code is specific to geometry collection	GeometryCollectionToDynamicMesh.h

Name	Remarks	Include Path
static int32 AppendMeshToCollection ( FGeometryCollection& Collection, const FDynamicMesh3& Mesh, const FTransform& MeshTransform, const FToCollectionOptions& Options )	Add a new mesh to the geometry collection Note this updates a Geometry Collection rather than the more general FManagedArrayCollection because some of the updating code is specific to geometry collection	GeometryCollectionToDynamicMesh.h
static TConstArrayView< FTransform3f > GetCollectionTransforms ( const FManagedArrayCollection& Collection )		GeometryCollectionToDynamicMesh.h
static FName InternalFacePolyGroupName()	Get the name used for the polygroup that we optionally set on the dynamic mesh, corresponding to the internal face tags of the geometry collection triangles.	GeometryCollectionToDynamicMesh.h
static bool UpdateCollection ( const FTransform& FromCollection, const FDynamicMesh3& Mesh, int32 GeometryIdx, FGeometryCollection& Output, const FToCollectionOptions& Options )	Update an existing geometry in a collection w/ a new mesh (w/ the same number of faces and vertices!)	GeometryCollectionToDynamicMesh.h
static FName VisibleFacePolyGroupName()	Get the name used for the polygroup that we optionally set on the dynamic mesh, corresponding to the invisible face tags of the geometry collection triangles.	GeometryCollectionToDynamicMesh.h
