Ultimate Engine CoPilot V2 Overview

About

Ultimate Engine CoPilot is an AI copilot that runs inside the Unreal Editor. You describe what you want in plain words, and it picks the tools it needs, builds the assets in your project and reports exactly what it changed.

It was one of the first copilots for Unreal Engine 5, and Epic Games has featured it on FAB more than once. Version 2 adds agents, hosted generation for meshes, audio and video, and a fully local studio.

Use it with the AI you prefer: a plan with AI tokens included, your own API key or a local model. A license is yours to keep, and no subscription is required.
