| ConceptualPanel | This panel maintains a collection of conceptual children that are neither logical children nor visual children of the panel. This allows those visuals to be connected to other parts of the UI, if necessary, or even to remain disconnected. |
| DisconnectedUIElementCollection | |
| DisconnectedUIElementCollection.DegenerateSibling | |
| DisconnectedUIElementCollection.SurrogateVisualParent | |
| Viewport3DEx | A Viewport3D subclass that shields Panel3D from needing to arrange the 3D models in a specific order. For models to be truly transparent, and have the models 'behind' them be visible, they must exist in the Children collection in the opposite order of the way you see them on-screen. The front model must be the last child, and the back model must be the first child (not including the scene's light source). |
