FishNetPhysicsSceneSync

The FishNetPhysicsSceneSync should be placed in any playable scene where characters will be active and physics is required. It should not be placed in the main menu or loading scenes.

Scenes created with the New Scene Wizard have this prefab automatically placed in them.

This prefab ensures that physics is properly simulated in any scene that is stacked. Scene stacking is the process of loading multiple scenes or copies of the same scene simultaneously on the server, such as instanced dungeons, and separating the physics so object in one scene do not collide with objects in another scene.

All scenes loaded on the server in online play mode are loaded as stacked scenes.
