Lighting Scene Operations

The default lighting scene defined in your profile is loaded on startup. That lighting scene remains loaded until SetLightingScene is called.

IMixedRealitySceneSystem sceneSystem = MixedRealityToolkit.Instance.GetService<IMixedRealitySceneSystem>();

sceneSystem.SetLightingScene("MorningLighting");

Lighting Setting Transitions

transitionType controls the style of the transition to new lighting scene.

IMixedRealitySceneSystem sceneSystem = MixedRealityToolkit.Instance.GetService<IMixedRealitySceneSystem>();

sceneSystem.SetLightingScene("MiddayLighting", LightingSceneTransitionType.CrossFade);

The available styles are:

Type	Description	Duration
None	Previous lighting scene is unloaded, new lighting scene is loaded. No transition.	Ignored
FadeToBlack	Previous lighting scene fades out to black. New lighting scene is loaded, then faded up from black. Useful for smooth transitions between locations.	Used
CrossFade	Previous lighting scene fades out as new lighting scene fades in. Useful for smooth transitions between lighting setups in the same location.	Used

Note that some lighting settings cannot be interpolated during transitions. If you want a smooth visual transition these settings will have to remain consistent between lighting scenes.

Setting	Smooth FadeToBlack Transition	Smooth CrossFade Transition
Skybox	No	No
Custom Reflections	No	No
Sun light realtime shadows	Yes	No
