Bounding Box Layer when specified is the layer to first test against before rolling back colliders. When a layer is specified a collider will be added to your ColliderRollback objects; because of this, be sure to use a layer which has no physics intersections and is not used for anything else.
Maximum Rollback Time is the maxium time colliders may rollback. Using a value of 1f would allow colliders to rollback at most one second in the past, which is a very reasonable amount of time given typical player latencies are less than 100ms.
Interpolation is the amount of interpolation you are using on your NetworkTransform components. If you are using rigidbodies with PredictedObject this would be the Spectator Interpolation value.
