A value that indicates how SceneKit should handle the node when rendering movement-related effects.
- iOS 10.0+
- macOS 10.12+
- tvOS 10.0+
- watchOS 3.0+
The node’s content is not affected by motion blur effects. (See the
motioncamera property, which applies motion blur effects for camera movement but not subject movement.)
The node does not contribute to environmental lighting of other objects. Environmental lighting is an aspect of physically based rendering (see
physically), in which surfaces tend to pick up the color of other scene content around them. SceneKit performs environmental lighting by rendering light probes—small, omnidirectional snapshots of the scene’s contents, as visible from at various points around the scene. Light probes are static, so nodes that are expected to move should not contribute to the lighting environment for other surfaces.
This value is merely a hint that communicates to SceneKit’s rendering system about how you want to move content in your scene; it does not affect your ability to change the node’s position or add animations or physics to the node.
