Unity AI and New AI Tools for Game Development — Video Examples

Unity AI, CLI, and MCP were invented to allow anyone to turn their ideas into reality without having to dive deep into the Engine. Unity AI is a great tool for accelerating your work. However, you should be careful:

• Use it as a helper.
• Double-check what it creates.

No AI will replace the Architectural Thinking of Passionate Unity Developers.

What people have experienced in 2026 is that quick AI-generated code snippets, without building a Proper Application Architecture, may be cheaper in terms of token usage for further AI Analysis, but they can turn a project into a collection of poorly connected pieces of code that are difficult for humans to maintain. But it’s good to see some Asset Publishers can still create HQ Products.

Unity AI Suite — Official AI Tools by Unity

Ultimately, Gamers will decide whether they want to play AI-created games or not. You can either embrace it and use it as a helper, or slow yourself down while others move faster.

Unity says these tools are primarily intended for prototyping. If you use generated art, you should replace those placeholders with final assets later. Code should also be reviewed and tested by Humans, especially when dealing with IAPs or Ads.

Use Case of Unity AI

I recently tried to ask Unity AI to implement a simple game with the only button from scratch. The result was wrong even with using Plan mode at first.

But when I asked Agent for some help instead (in addition to my interventions), Unity AI was pretty good. For example, creating new 3D Animation for the model from the Unity Asset Store.

So, “Augmenting Workflows” is probably the best way to describe how Unity AI should be used.

Subscription Auto-Renewal and Cancellation

Auto-renewing is not a problem, you can assign the reminder or event in the calendar to disable that if you need — this is the common rule for subscriptions, or cancel it in one day:

1. Register for Unity AI.
2. Cancel the subscription.
3. You have 14 days for free.

Does canceling feel like a maze? — Yes, it does.
Is it a scam because it’s promoted as Free? — No, it isn’t.

You can cancel it on cloud.unity.com.

You enter your credit card’s data when registering. Furthermore, you have to read all the conditions and FAQ on the page before entering your data — ultimately, this responsibility lies on the user’s side.

Could it have been more human? Possibly, with more email notifications.

Unity’s Plugin for Third-Party Agents

Unity’s plugin for Claude Code, Codex, and Grok adds a set of Unity skills to your AI agent. This isn’t a Unity Asset Store plugin or package and you can’t install it through the Package Manager. After installing, your agent uses skills to load relevant context to accomplish tasks you give it in your Unity project.

Claude Code

Unity released an Official Plugin for Claude Code with 29 curated native engine skills at launch for Game Development and Performance Optimization. Skills load automatically when you work on a Unity project in Claude Code:

• URP Post-Processing, Render Graph, Shader Graph,
• uGUI, UI Toolkit, IMGUI, TMP,
• 2D and Tilemaps,
• Audio and Vivox Voice Chat,
• AI Navigation and 3D Collisions (Physics),
• LevelPlay, IAP, and Live Ops,
• Multiplayer,
• Localization and Optimization for Web.

The Agent now approaches common Unity development tasks with the official Unity guidance instead of assembling an answer from third-party sources. In short, it’s cheaper, faster, more reliable, and with updated knowledge. Claude works from Memory: no Unity Plugins, configuration, or per-project setup.

Is it better than Bezi?
I just provide here 2 official statements:

• Bezi is an agentic workspace that Sits On Top of Your Engine – from Bezi website.
• Unity’s Plugin is a Direct Editor Control, connecting Claude Code to your active project with official Unity support and security – from Discussions.

Codex and OpenAI

The Official Tool for OpenAI Codex (GPT-6 Astra) is available with 31 skills (Unity will continue adding more Skills), first-party integration, and Direct Engine Expertise. You just need to understand what it is NOT:

1. Knowledge from old Forum Posts, Tutorials, or Sample Code written Many Years Ago — Unity’s Engineers with expertise in different areas of development who actually build the engine put their vision and experience into the appropriate skills, taking the current versions of Unity into account.
2. MCP server — running Editor makes no sense here, the Agent works Directly with Project files using the Unity CLI.
3. Mom for a Child Robot. Only You Can Inspire the Machine. AI is Nothing without the Source. Humans are the Source of Current Civilization.

AI in Unity for 3D Models — UModeler X + PicoBerry

The UModeler X plugin for Unity Editor is now free and provides real-time 3D modeling, UV editing, texturing, mesh optimization, and rigging directly inside the Unity Editor. It introduces a new AI generation tool (PicoBerry) for creating Images and 3D Models with just a few clicks.

In this video example, I experimented with creating a cartoon version of the Donald Trump character and got a low-poly result in about a minute.

Each Month, you can generate several models for free and accelerate your game development. Generate production-ready 3D assets with PicoBerry AI:

1. Describe Your Asset using text or image as prompts.
2. AI creates your 3D model in 30–90 seconds.
3. Refine with UModeler X and AI: remeshing, texturing, and rigging.
4. Ship It: Game-ready assets, straight into your project.

Smart Remeshing

AI-powered topology optimization automatically cleans up mesh geometry. Get game-ready polygon counts without manual retopology work.

AI Rigging

Automatically generate bone structures and skin weights for your characters. Go from static mesh to animation-ready model in a single click.

AI Texturing

Generate and apply high-quality textures with AI. PBR-ready materials created from text descriptions — seamlessly mapped to your 3D models.

Start on Web — Continue in Unity

You can generate content in the web version of PicoBerry in your browser and then access everything in the plugin for Unity Editor. This method is useful when traveling. All Generated AI Models will be seamlessly synced to your Unity project.

AI Slop and Negative Reviews

One thing I’ve noticed is that many of the people sharing the most negative emotions about AI, Unity AI, often have empty profiles on Social Media. That’s a strong indicator. It’s better to put that energy into creating games rather than leaving comments like these. You Can’t Stop the Progress of AI.

Moreover, the LinkedIn audience provides More Valuable and Professional Feedback than the YouTube audience below (source). So, where you communicate is up to you.
