Performance on our program struck on Model3DCollection.Add method
We often adds and removs GeometryModel3D from screen, and adding models to Model3DGroup.Children -> Model3DCollection takes 20% of performance.
Reduce the number of models addid to Model3DCollections is impossible. All objects and materials are freezed.
Can someone helps?
It would be very useful to have a method like Model3DCollection.AddModels for adding a set of models without having to fire changed events.
