Thrixel

The AI platform for creating and editing 3D assets

[Rana Hanocka @RanaHanocka]

Fable + Thrixel built this peaceful fishkeeping demo in UNREAL ENGINE 🎮

The agent chose a Japandi style, created the assets with Thrixel, populated the Unreal level, and built the gameplay logic.

Build World now supports Unreal. Tell your agent what you want to build 👇

[Rana Hanocka @RanaHanocka]

@S0ultel @DanKornas we have "style guides" - you can upload text, PDFs, images, meshes, etc. as references, and every new asset automatically uses that context to keep the world consistent/in the same style.

[Dan Kornas @DanKornas]

Building a 3D prototype gets slow when your coding agent also has to make every asset.

Build World is a Thrixel skill and connector for builders creating interactive 3D worlds with an AI coding agent.

It helps you move from a plain-English game or experience prompt to an interactive world by letting the agent handle scene logic and interactions while Thrixel generates and manages the 3D assets.

Key features:

• Agent-led scene setup – your coding agent handles the world logic, interactions, and scene setup
• Thrixel asset workflow – generate, organize, and manage 3D assets through Thrixel
• Multi-engine support – the workflow currently supports Three.js, Roblox, Unity, and Unreal Engine
• Claude Code plugin path – one plugin installs both the Thrixel skill and connector
• Shareable publishing – ask the agent to publish a finished world and receive a live link without separate hosting setup

Built a 2D platformer adventure in @threejs using a single prompt with @OpenAI Astra + @thrixelinc . 🤯

Inspired by Donkey Kong Country Returns, but with original characters, worlds, and level themes.

Astra + Thrixel → From a single prompt to a playable adventure.

This is the workflow we want more of: one agent mocks up the scene, hands off to a specialist for the actual 3D assets, and the pipeline picks the right tool per asset type.🔥

@RanaHanocka I am not sure If I am missing something or some previous use case of Astra but this is one of the most impressive ai game I have seen, not by it's complexity but given how clean it looks. Do you know how much did it cost for thrixel to generate the assets ?

[Rana Hanocka @RanaHanocka]

Astra + Thrixel just built this 3D platformer from a single prompt. 🤯

Astra mocks up the scene, then calls Thrixel to generate the editable 3D assets. Depending on the asset’s role (background prop, animation), Astra picks the best Thrixel creation pipeline.

Excited to have Thrixel support the Chicago Claude community! Really fun getting to hear about what people built with Thrixel last night. Lots of creative ideas and some awesome projects 👏

[Thrixel @thrixelinc]

This week, Thrixel participated in the Chicago Claude Community Build Day! 🎉

We saw tons of imaginative assets and clever ideas. One of the standout builds was an interactive, game-like experience built by https://t.co/w6RNs8MPrU for practicing conversational Spanish. We'd like to extend our thanks to Todd Walton for organizing the event.

Agent-first 3D is opening the field to a whole new wave of builders. What would you create? ⚒️

ASTRA + Thrixel built this ENTIRE 3D sci-fi rail shooter from 1 PROMPT 🚀

ASTRA orchestrated the entire build and scene assembly, calling Thrixel to create the high-quality, agent-ready 3D assets.

Had so much fun taking the stage at Three.js Conf Paris to talk all things Thrixel 🚀

From a single prompt to a complete world in Three.js - Thrixel is changing the way we build interactive 3D.

[Rana Hanocka @RanaHanocka]

Think you can beat her score? She’s crazy fast 👀

Astra + Thrixel built this movement shooter from one prompt 🤯

One of our teammates is obsessed with speedrunning, so she used Build World to create the exact game she wanted to play.

Build the games YOU want to play.

Every Build World creation can be published to a live link, so you can instantly share your interactive world with anyone.

[Rana Hanocka @RanaHanocka]

Astra + Thrixel built this cozy alien marketplace in Three.js in 1 prompt 🤯

Astra is faster and better than Opus/Fable at wiring up the game logic and building out the scene.

Build World connects any agent to Thrixel as its 3D creation engine.

Prompt-to-World is here 🤯🌍

We’ve seen some incredible AI-generated videos recently. Now it’s time to actually step inside one.

Generate a FULLY interactive 3D world from ONE prompt using Claude + Thrixel’s Build World skill.

Jump in and explore the aquarium yourself 🦈🐠👇

[Rana Hanocka @RanaHanocka]

Build World from Thrixel pairs your AI agent of choice with Thrixel’s high-quality, intelligent 3D creation technology to build interactive, playable worlds.

Supports Three.js, Unity, and now Roblox. More engines coming soon!

Claude + Thrixel Skills built this entire Roblox game from ONE prompt.

Everything was built autonomously:
• Every 3D asset
• Every game mechanic
• All logic & scene setup

Today, we’re expanding Thrixel Skills to include Roblox. Excited to see what you build! 👇

[Eliannah Linehan @Eliannah]

Vibed this game with my 5yo over the weekend, fully playable in 1 prompt, tweaking it was the fun part.

We tried this a year ago and it was not possible - today it's actually insane.
