Ultimate Engine Co-Pilot V2: The Plugin That Changed Unreal Engine Forever

Ultimate Engine Co-Pilot (formerly Ultimate Blueprint Generator) was the first AI Co-Pilot for Unreal Engine. Since 2025 it’s been used on real projects to generate Blueprints, materials, Niagara systems and gameplay logic inside UE5, and it got Featured on Fab by Epic Games multiple times.

Over twenty updates in a little over a year. We ship, and we do not stop.

You gave us feedback. Me and Ashley, my co-dev, listened. And then…

We completely rebuilt everything.

The others are just now catching up to where we started. V2 is not where they’re headed.

Our existing tools? Reworked. Improved. Adapted. But V2 isn’t just a UI refresh. It is a massive leap in what an AI agent can actually do inside your editor. Here is what we’ve been building non-stop for the last few months.

• Blueprint generation that wires the graph and lays it out like a human would.
• Blueprint to C++, with a live preview before you commit.
• Local generation of 3D models, textures, images, sound and video, right in the editor.
• Run it on your own machine. No API key, no cloud, no per-use cost.
• An agent that knows your project, your design doc, and even your editor’s UI.
• A crew of agents to hand work to while you keep building.
• 1,563 tools across 37 subsystems, on UE 5.5 to 5.8, Windows and macOS.

Stick around to the end. I have a few quick questions waiting, and each one drops bonus tokens straight into your account for answering.

Blueprint generation got massively better

Prompt-to-Blueprint isn’t new. What’s new is that it finally works the way you always wanted it to.

You type what a function should do. The nodes appear. They wire themselves, with far more precision, and the layout comes out human readable.

Branches, loops, function calls, early returns, math logic. V2’s synthesize_graph builds the nodes, the pins, and the exec/data wiring. We reworked node arrangement too, so what lands in your graph is laid out like a person did it, not a pile you have to untangle first.

It won’t overwrite work it didn’t author (unless told to), and it adds to existing functions without breaking your current logic.

It knows your project

The Project Scanner has been reworked. It indexes faster, understands more of what it finds, and keeps up as your project changes instead of going stale the moment you rename something.

AI memory got the same treatment. It holds your conventions, your naming, the way your systems are actually put together, so you stop re-explaining your own project at the start of every session.

And you can hand it your design doc. Game Design Document ingestion is reworked in V2. Drop the GDD in and the agent works from your design and your terminology instead of generic Unreal defaults.

This is the part users tell me matters most, and it is the reason the rest of this list works. An agent that knows your project gives you specific answers. An agent that doesn’t just guesses.

It can see your editor. And use it.

Every AI tool for Unreal is stuck behind the same wall: it can only touch what the engine exposes as an API. Hit a panel nobody wrote a scripting interface for, and the agent is blind.

V2 doesn’t have that wall.

It works the way you do:

• Takes a screenshot and actually looks at it.
• Reads the live widget tree of your editor.
• Clicks, types, drags, ticks a checkbox, picks from a dropdown, or hits Ctrl+S.

If a panel exists, it can drive it. API or no API.

And it works in reverse. Ask where something is, and it draws a box and an arrow on your screen and points at it. No more “go to Window, then Developer Tools, then scroll down”. It just shows you.

This one is still experimental, and it is getting sharper with every build.

Local generation is the future

Local generation of video. Local generation of sound. 3D models. Images. All inside your editor.

Prompt-to-asset is no longer a web browser novelty where you download zips to your desktop. Text goes in. A textured Skeletal Mesh, a MediaSource video, or an audio file comes out. It lands directly in your project, already imported and ready to drag into the viewport.

Local Studio: your own AI workspace

Your models. Your machine. Your assets.

We built the ultimate local AI workspace. Local Studio is a dedicated environment running on your own hardware. One click to install Ollama, browse models, and pull them straight from the editor.

Then it goes past chat. Video, images, sound and 3D models can all be generated locally, on your own models, on your own GPU. No API key. No cloud round trip. No per-generation cost.

We also reworked how the plugin talks to a local model. Tool calling is far more reliable than it was in any previous version, and we spent months on token optimisation, so a local model spends its context on your project instead of on overhead.

For a long time, running a local model against a real editor meant it quietly received a fraction of what it was sent, then did something useless with it. You blamed the model. We fixed it. V2 handles it silently, so local models finally see the editor the way they were supposed to.

Fair warning: this wants a capable machine. For real work you want a strong GPU, but to test the waters, a laptop with 32GB of RAM and a decent GPU can already get things done. Before V2 the bar was far higher, and running the plugin’s tools locally needed an extremely powerful rig. We brought that down a lot.

For now, a local model still won’t match a frontier one like Claude Opus, Claude Sonnet or GPT. But it costs you nothing to run, it’s genuinely good enough to work with, and it’s yours.

Your own AI development team

Why wait for one task to finish? V2 introduces Subagents and Crew. Delegate work to named AI roles (with specific permissions) and keep working in the editor. Run five tasks at once. Let a Worker agent build the logic and a Reviewer agent check it. Everything ticks to green in the background while you focus on your game.

It teaches you the engine

This one I didn’t plan. People kept telling me the same thing: they bought a Co-Pilot and ended up learning Unreal.

It makes sense in hindsight. Ask for a Blueprint and watch the nodes appear, wired correctly, with the right pins connected in the right order, and you have just read a worked example. Ask why it did something that way and it tells you.

V2 rebuilds the entire Learn tab around it. Courses tick themselves complete when you actually do the thing in the editor, not when you click a button saying you did. XP, levels, achievements and a leaderboard sit on top, so you can see how far you have actually got instead of guessing.

Memory helps here too. It remembers what went wrong last time, so your second attempt at a system starts ahead of your first.

All of it ships free with the plugin.

If you are learning Unreal Engine, this is the part I would point at.

Scale: 1,563 tools across 37 subsystems

We didn’t just add features. We scaled the absolute core of what this tool can touch.

Tools	1,563 - the largest editor toolset on the market.
Subsystems	37 Extensions - Animation, Niagara, GAS, Physics, UI, Materials, and more.
Languages	19 - Fully translated UI shipping natively in the plugin.
Engine versions	UE 5.5 - 5.8
Platforms	Windows and macOS

We also rebuilt the shell from the ground up. Project search is instant. AI memory is smarter and remembers failures. Source control works beautifully across git, Perforce, and Diversion without needing their respective plugins enabled.

(And yes, for the programmers who’ve been asking: V2 now includes an in-editor Blueprint to C++ converter with a live preview panel.)

The Wait is Almost Over

V2 is built by me and Ashley, my co-dev. Two people who wanted to make Unreal Engine faster, smarter, and yours.

We are also bringing an affordable new way to start using the plugin, with more detail at launch. On top of that we are reworking the entire documentation for V2, and cutting a new trailer and a fresh overview video to go with it. All of that takes time, and we would rather get it right.

If you already own the plugin, V2 will be a completely free update the day it goes live, straight from downloads.

In the meantime, the best place for updates, and a heads up the day it drops, is our community on Discord.

The biggest update in our history is close.

ETA: 17 to 26 September 2026.

Before you go, thank you

Recently a lot of you filled in our feedback form. I read every single response, and it genuinely shaped V2 in the last stretch. Some of the things landing in this update exist because one of you asked for them. So, thank you. It helped more than you know.

I want to keep that going. Below are three quick questions. They take under a minute, and each one drops bonus tokens into your account as a thank you.

The bonus tokens are for plugin owners. If you don’t own it yet, your answers still help, and there is $15 off waiting in the box above.
