The Unity plugin: Zetta 3D and an AI agent, inside the Editor
Generate and finish 3D models, import them in one click, run pipelines, and build your game with an agent that reads your scene and writes C#, in Unity.
What it does
Every Studio tool, docked
Generate 3D, Smart 3D, segmentation, retopology, Smart UV, texturing, rigging, conversion and the Image Studio, with the web Studio’s engines and settings.
Into the project in one click
Finished models import into your Assets folder and can be placed in the open scene; drag any model from your library into the Scene view.
The Zetta Agent
A game-development assistant that reads your project, writes and fixes C#, builds prefabs and materials, tests in Play Mode and makes the art it needs.
Your own API key
Run the agent on your own Gemini, OpenAI, DeepSeek or Claude key, on any plan — pick the model and thinking level yourself, billed by the provider.
Pipelines, from Unity
The same node-canvas recipes as on the web, run on up to 20 pictures or models at once, with the results imported into your project.
How it works
- Install the packageIn Unity’s Package Manager, add the plugin from its Git URL. Unity fetches everything it needs with it.
- Sign inThe 3D Studio window opens on its own. Sign in with your browser and click Connect Unity — the Editor never sees a password.
- Make, or askGenerate and finish models in 3D Studio, or tell the Agent what you want built. Everything lands in your library and your project.
What people use it for
- Props and characters generated and placed while blocking out a level
- A rigged character with Unity Humanoid bone names, imported straight into the project
- Gameplay scripts written, compiled and tested by the agent in Play Mode
- A batch of props run through one pipeline and imported into the project together
- Finding out why something in a scene is broken, with Ask mode changing nothing
- A studio that already pays for Gemini, OpenAI, DeepSeek or Claude running the agent on that key
What it cannot do
- Gaussian splats and worlds are listed but cannot be used in Unity; they open on zetta3d.ai
- Installed from a Git URL, so Git must be installed; it is not on the Unity Asset Store
- Your own API key covers the agent only; making 3D models and pictures always uses Zetta credits
- Needs Unity 2022.3 LTS or newer
- Source-available, not open source — the code can be read and audited, not modified or redistributed

Common questions
Does the Unity plugin cost anything?
No to install. What you make with it uses your Zetta 3D account exactly as the web does — credits for models, AI tokens for the agent — with your plan’s limits. Run the agent on your own API key instead and its work is billed by that provider.
PricingWill the agent change my project without asking?
By default it asks before deleting anything, making or processing a 3D model, or running a pipeline, and every change it makes is on the Undo stack. Ask mode changes nothing at all.
