3D AI game maker: make 3D games by describing them

A 3D AI game maker should get you from an idea to something you can walk around in. Shiny Gen builds 3D games from a description on the Godot engine, or on an N64-class engine for retro 3D, and gives you a built-in 3D editor for the models and worlds. It runs in your browser.

Shiny Rapids, a 3D rafting game on the Godot engine, made with AI

Where your 3D game runs

Godot, in the browser

Games are written in real GDScript on our Godot build, which has a WebGPU renderer. The whole engine runs in the browser with nothing to install, so a 3D game is a link you can send. You can also export it for the web as a zip you host anywhere (any one purchase, from $2.99).

N64, GameCube, and DS engines

For retro-style 3D, the N64 engine is an N64-class engine we wrote, with its own RSP microcode, and there are GameCube and DS engines too. They compile games into a ROM, a .dol, or a .nds file, within the limits of those consoles. They are not emulators.

All six engines are explained on the engines page.

How a 3D game gets made

  1. Describe it. "A low-poly river raft game. Hold left or right to paddle. Rocks knock planks loose." Pick the Godot engine and send it to the Agent.
  2. The AI builds and tests it. The agent writes the game, runs it, takes screenshots, presses the controls, and fixes errors, so you start from something that runs.
  3. Shape the 3D content. Open the 3D editor to build and edit meshes, entities, and worlds, or generate and edit images with AI and turn them into entities in a 3D world.
  4. Keep going by chat. Ask for a new level, a camera change, or a faster enemy. Share a link when it plays right.

3D games from the catalogue

Play any of these without an account, then remix one into your own copy. Retro 3D games run at the resolution of the console they are made for.

What is in the 3D toolkit

ToolWhat it does
3D model editorBuild and edit meshes, entities, and 3D worlds
Image editorGenerate and edit images and sprites with AI, then go straight to creating entities in a 3D world
AnimationGenerate sprite animations with video models
AudioGenerate sound effects and music as editable scores
AgentWrites and fixes the game, and plays it to check
It is a whole game engine, not only a renderer: physics, scenes, and tools are already there, so you are not hand-coding them. The honest limit is that the project runs on Shiny Gen's own Godot build and does not open in the stock Godot editor.

The same editor and agent are in the iPhone, iPad, and Android apps, in 17 languages.

Questions about the 3D AI game maker

What is a 3D AI game maker?

A tool where you describe a 3D game and an AI builds it, instead of you modelling and coding everything first. In Shiny Gen the agent writes the game, runs it, and fixes errors, and you shape the 3D content with a built-in editor.

Which engine makes the 3D games?

The Godot engine, in a build we made with a WebGPU renderer, for 3D games that play in the browser and the apps. For retro-style 3D there are the N64, GameCube, and DS engines, which work within those consoles' limits.

Can I edit the 3D models myself?

Yes. The built-in 3D editor lets you build and edit meshes, entities, and 3D worlds by hand. You can also go from the image editor straight to creating entities in a 3D world.

Do I need to install anything?

No. The whole engine and the editors run in your browser. The first load is about 17 MB. There are also iPhone, iPad, and Android apps.

Can I open the project in the regular Godot editor?

No. The games run on Shiny Gen's own Godot build with extra features, so the project does not open in the stock desktop Godot editor. The code is real GDScript you can read and edit in the app.

Is it free?

You can make, play, and share for free. AI generation spends gems: you start with free gems and a few free AI turns, then get one free AI prompt each day, and gem packs start at $2.99.

Can I make a 3D game for the N64?

Yes. The N64 engine is an N64-class engine we wrote, including our own RSP microcode. You can export a ROM (any one purchase, from $2.99). It has been tested in an emulator, not yet on real hardware.

Can the AI make the models and textures too?

It can generate images, edit them with AI, and build 3D content in the editor, and it can generate sound and music. Generation uses gems, and the agent says how many before it spends them.

Build something you can look around in

Describe a 3D game, play what the AI builds, and shape it in the editor.
