How We Synchronized Editing for Rec Room's Multiplayer Scripting System

Rec Room's Circuits is a multiplayer-synchronized scripting system that lets players build interactive experiences. The team evolved from V1 (using per-object synchronization with scalability limits) to V2, which consolidated all state into a single game object. After encountering cross-object consistency issues with an in-memory database approach, they adopted a Redux-inspired architecture where all state changes flow through a single reducer function.
