This sample demonstrates how to move multiple Entities and support for HDRP Motion Vectors making Entities react correctly to Motion Blur

The scene contains sphere GameObjects parented to Balls GameObject. Each sphere contains Sphere Id Authoring component attached which gets used by StressTestScenes/BigBatches/MoveBallsSystem.cs script iterating through each sphere id and translating all sphere entities each frame.

1. In the Hierarchy, select any Sphere parented to Balls GameObject
2. In the Inspector, note that ConvertToEntity and the Sphere ID Authoring components are attached
3. Enter Play mode. All spheres are converted to Entities and change their position with a trail of Motion Blur
