Renders the panel as an object within the 3D world.
The panel is rendered by one or more cameras at a specified world-space position and can be occluded by other objects in the scene. This mode is suitable for in-world UI such as interactive screens, billboards, or diegetic interfaces. Depending on camera order, it can also be used as an overlay if, for example, you only want to add the ability to have a 3D rotation to the UI.
