World Manager

Build dynamic and responsive worlds with a powerful, lightweight Blueprint framework for Unreal Engine.

World Manager provides a centralized world time system that automatically manages day and night cycles, sunrise and sunset calculation, dynamic sun and moon rotation, multiplayer synchronization, and event-driven gameplay.

With built-in support for Sky Atmosphere, Exponential Height Fog, and customizable lighting overrides, your environment automatically adapts to changing world conditions while remaining fully configurable.

Designed around a modular event-driven architecture, gameplay systems, AI, audio, UI, and environmental actors can react naturally to world state changes without constant polling or complex Blueprint logic.

Whether you're creating prototypes or production-ready projects, World Manager offers an easy-to-integrate solution that keeps your entire world synchronized from a single actor.
