Each Player Ran a World Model. Their Views Still Had to Agree.
WorldCast exchanges player and scene states between local generators instead of coordinating every view through one central generator.
Summary
WorldCast exchanges player and scene states between local generators instead of coordinating every view through one central generator.
WorldCast gives each player a local video generator and state model, estimating position from generated video and controls. Clients exchange player states, project them into camera-aligned fields and share scene information so independently generated views can remain consistent. Counter-Strike 2 experiments reported real-time clients and player-rendering rates more than an order of magnitude above joint-generation methods. Shared scene state improved appearance consistency across whole rounds, and image quality remained stable in hour-long rollouts. The system exchanges states rather than centrally generating every view. This is an experimental multiplayer world-model architecture, not an announced online game or a guarantee of consistency in arbitrary environments.
