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 5.8
• PCGExtendedToolkit — Core PCGEx plugin (free, MIT licensed); this port targets commit 866c7c16
• ZoneGraph — Epic's experimental ZoneGraph plugin (included with the engine)

UE 5.8 port provenance

This UE 5.8 port starts from Evan Seaward's pinned fork commit a5e7fc89 of Timothé Lapetite's original PCGEx ZoneGraph plugin. The original project metadata, authorship, links, and MIT license are preserved; the port only updates engine and PCGEx compatibility.
