Scene system overview

When to use the scene system

If your project consists of a single scene, the Scene System probably isn't necessary. It is most useful when one or more of the following are true:

• Your project has multiple scenes.
• You're used to single scene loading, but you don't like the way it destroys the MixedRealityToolkit instance.
• You want a simple way to additively load multiple scenes to construct your experience.
• You want a simple way to keep track of load operations in progress or a simple way to control scene activation for multiple scenes being loaded at once.
• You want to keep lighting consistent and predictable across all your scenes.

How to use the scene system

• Scene Types
• Content Scene Loading
• Monitoring Content Loading
• Lighting Scene Loading

Editor settings

By default, the Scene System enforces several behaviors in the Unity editor. If you find any of these behaviors heavy-handed, they can be disabled in the Editor Settings section of your Scene System profile.

• Editor Manage Build Settings: If true, the service will update your build settings automatically, ensuring that all manager, lighting and content scenes are added. Disable this if you want total control over build settings.

• Editor Enforce Scene Order: If true, the service will ensure that the manager scene is displayed first in scene hierarchy, followed by lighting and then content. Disable this if you want total control over scene hierarchy.

• Editor Manage Loaded Scenes: If true, the service will ensure that the manager, content and lighting scenes are always loaded. Disable if you want total control over which scenes are loaded in editor.

• Editor Enforce Lighting Scene Types: If true, the service will ensure that only the lighting-related components defined in PermittedLightingSceneComponentTypes are allowed in lighting scenes. Disable if you want total control over the content of lighting scenes.
