What is PCGEx + ZoneGraph?

This is a companion plugin for PCGEx that bridges PCGEx cluster data with Epic's ZoneGraph plugin, converting cluster topology into ZoneGraph data for AI navigation.

Experimental Status

Epic's ZoneGraph plugin is experimental. Epic warns that "ZoneGraph will have API breaking changes as its development progresses." If something breaks, open an issue and I'll look into it.

Requirements

  • Unreal Engine 5.7+
  • PCGExtendedToolkit — Core PCGEx plugin (free, MIT licensed)
  • ZoneGraph — Epic's experimental ZoneGraph plugin (included with the engine)

Installation

PCGEx + ZoneGraph is not available on FAB as the platform does not allow cross-plugin dependencies.

From Source

  1. Clone this repository into your project's Plugins/ folder
  2. Ensure PCGExtendedToolkit and ZoneGraph are both enabled
  3. Regenerate project files and build

License

This plugin is source-available

  • Personal use — Free. Individuals may use, copy, and modify the plugin for non-commercial and personal projects at no cost.
  • Studio / Professional use — Requires a license. Not currently on FAB, so licensing is handled directly through a custom license agreement.
