FSelectionFacade | Unreal Engine 5.7 Documentation

Defines common API for storing a sib indexing of a separate group. For example, to store a subset of vertices defined in the group "VerticesGroup", use the function : Key = this->AddSelection({1,2,3,4}); The key can be saved and later used to query the values: TArray SavedVertices; this->GetSelection(Key, SavedVertices);

The following groups are created on the collection based on which API is called.

= FSelectionFacade::UnboundGroup_

FindAttribute>(FVertexSetInterface::IndexAttribute, );

= FSelectionFacade::WeightedUnboundGroup_

FindAttribute>(FVertexSetInterface::IndexAttribute, );
FindAttribute>(FVertexSetInterface::WeightAttribute, );

= FSelectionFacade::BoundGroup_

FindAttribute>(FVertexSetInterface::IndexAttribute, );
FindAttribute(FVertexSetInterface::BoneIndexAttribute,);

= FSelectionFacade::WeightedBoundGroup_

FindAttribute>(FVertexSetInterface::IndexAttribute, );
FindAttribute>(FVertexSetInterface::WeightAttribute, );
FindAttribute(FVertexSetInterface::BoneIndexAttribute, );
