The underlying Relay service within the Multiplayer Services SDK has the following limitations:
-
Relay is engine agnostic. If you use Relay with Unity, the recommended best practice is to use the Multiplayer Services SDK. Use with
SessionOptionsto configure a session to use Relay networking.WithRelayNetwork - Players can only connect with other players within the same session.
- Currently, there's no region-locking functionality; anyone can request an allocation in any region if the region has enough capacity to support the request.
- The Relay service routes all communication through a single region selected by the host. As a result, cross-region communication might not offer optimal latency.
- A maximum of 150 players can join the host in the same session. Not all game types will scale to that high amount of players without the use of a dedicated game server. Carefully consider the impact on the host player when attempting high player count sessions with Relay. This limit's aligned with the maximum number of players allowed in a Lobby.
