Real-Time on FantasyMaps

OFM Shared World

Fri, 24 Apr 2026 12:00:00 -0500

A FoundryVTT module that lets one table see, live, what other tables are doing across the same fantasy world. Foreign players render as lightweight canvas sprites — no tokens are spawned, no database is written to, no permissions need wrangling. The first concrete piece of the long shared-world vision.

It connects to a geomqtt broker over MQTT, subscribes to the tiles your viewport is showing, and draws whatever moves through them. Compatible with Foundry v11–v13.

A small daemon that bridges Redis’s geospatial commands and an embedded MQTT broker. Drop tile-keyed coordinates into a Redis GEO set; any client subscribed to the matching tile topic gets the update on the next tick.

It is the transport layer that makes the rest of the shared-world experiments possible — Foundry tables, web clients, and Unity/Unreal sessions can all listen on the same tiles and see each other move.

OFM Unreal

Mon, 20 Apr 2026 12:00:00 -0500

An Unreal Engine plugin that consumes an Open Fantasy Maps style and assembles a scene hierarchy from its layers — at runtime or in-editor. Filters layers, evaluates Mapbox-style expressions, maps map features to actors via Blueprints, and pulls live overlays from geomqtt.

The bridge that puts the atlas inside the engine where the game already runs. The Unity counterpart lives at OFM Unity.

The Unity counterpart of OFM Unreal: an in-engine bridge that takes an Open Fantasy Maps style and walks its layers into a Unity scene. Layer filtering, feature-to-prefab mapping, and live overlay updates over geomqtt.
