Remarks

Get an attribute array with the given type and name. The attribute type must correspond to the type passed as the template parameter.

Example of use: TVertexAttributesConstRef VertexPositions = VertexAttributes().GetAttributesRef( "Position" ); // note: assign to value type for( const FVertexID VertexID : GetVertices().GetElementIDs() ) { const FVector Position = VertexPositions.Get( VertexID ); DoSomethingWith( Position ); }

Note that the returned object is a value type which should be assigned and passed by value, not reference. It is valid for as long as this TAttributesSet object exists.
