3D Game Maker — Build a Playable 3D Game

One sentence becomes a playable 3D scene — real geometry, a character who answers, and an ending you pick.

Liyue Harbour at night — a walkable pier with lanterns and an objective marker

A Shibuya street at 23:04 — neon shutters, a wet crossing, a red curtain above

A school rooftop at dusk — railing, water tower and the city below

Vought Tower lobby — marble, gold inlay and the reception desk

Liyue Harbour — Night Lanterns — Xiangling opens on the pier: portrait, dialogue box, one objective. — **Liyue Harbour — Night Lanterns** — Xiangling opens on the pier: portrait, dialogue box, one objective.

LIVE PROOF

The scene is one part of the world.

Neta Studio is an AI world builder — cast, map and story live in one world, and the 3D scene is one thing it ships. The character standing in it can walk into a roleplay or a visual novel next.

Geometry, not a picture — buildings, lanterns and railings are real meshes; the camera orbits, zooms and follows the character.

A character who answers — the scene reads the world’s cast, so the person you meet arrives with a name, a face and lines that fit.

Playable on the first build — one link, desktop and phone, touch stick included, nothing to install.

Questions, answered.

Do I need to know Three.js?

No. You describe the place and the scene is built. You can open the code afterwards, but nothing about the first build needs it.

What can I actually make?

A walkable night scene, a short choice-driven story, a diorama you can circle, or the set for a longer game. Each build is one screen you can finish in a sitting.

Can I use characters from my own world?

Yes. Name them and the scene uses that cast — the four games above come from Genshin Impact, Jujutsu Kaisen, Horimiya and The Boys worlds.

Does it work on a phone?

Yes. A thumb stick to walk, drag to look, pinch to zoom. Dialogue and choices sit inside the thumb zone.

What do I get at the end?

One published web work with a public link, plus its source files inside the world, so you can edit or embed it later.

Can I change the scene after it is built?

Ask in the same world — move a building, add a line, change an ending. It edits the work instead of starting over.

How long does one scene take?

Minutes rather than days. The geometry is generated, and the cast and dialogue come from the world that already exists.

Do I need models, textures or a rig?

No. Scenes are built from generated geometry and canvas textures, so there is no asset pack to buy and nothing to import.

Start with one place and one decision.

Describe the scene, and the game arrives with a camera, a character and an ending.
