System objects are a category of special, predefined intangible objects that can be placed in a scene for various effects. These categories include audio emitters, light sources, and interactive objects like spawn points. You can access system objects while editing a scene by clicking the System Objects tab of the Inventory panel. You can then filter your search by clicking All, Lights, Audio, or Interactive.
While editing a scene, system objects are represented by abstract shapes, but they are otherwise invisible while visiting the scene.
System object lights are intangible sources of light that can illuminate your scene. Each type of light operates differently; make sure to choose the right light for each situation. For more information on working with lights in a scene, see Working with lights.
The spawn point represents the exact location where visitors enter your scene. If you place more than one spawn point in the scene, visitors can potentially arrive at any of them, chosen at random:
Position - The location where visitors enter the scene.
Rotation - The direction visitors face when they enter the scene.
Scale - Has no effect.
