SceneSceneCommandBufferVersion Property

SceneCommandBufferVersion increases each time the Scene's command buffer is newly recorded. Usually this is done after the structure is changed (for example when a new SceneNode is added or removed, or when a material index is changed). When only Scene based data (matrices or materials) is changed, then only FrameDataVersion is increased, but not SceneStructureVersion.
