FChaosVDSceneStreaming | Unreal Engine 5.7 Documentation

API > API/Plugins > API/Plugins/ChaosVD

Simple pseudo level streaming system that works with a collection of ChaosVDSceneObjects - This system only updates a desired streaming state (from multiple threads) and issues a sync request in the GT. How these actions are executed depends on the implementations of each ChaosVDSceneObjects derived object
