Overview
PolyZones is an Unreal Engine plugin for building trigger and overlap volumes as custom polygonal shapes. It is built for spaces where box and sphere volumes are simply too crude, like irregular interiors, angled boundaries, and gameplay spaces that need tighter control.
The project is fully open source under the MIT license, so you can inspect it, change it, and wire it into your own workflow without nonsense.
The Fab version is there if you want one-click installation through Epic Games Launcher or just want to directly support continued development.
Supports Unreal Engine 5.0+
