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 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 the Sphere ID Authoring components are attached
3. Enter Play mode. All spheres are baked to Entities and change their position with a trail of Motion Blur
