3dx

Save any public Meshy or Tripo 3D model as a ready-to-use GLB.

One command. Textures, previews and metadata included.

If this saved you time, a ⭐ helps other 3D folks find it.

Why 3dx

• Paste a link, get a GLB. No accounts, no DevTools, no copy-pasting signed URLs.
• Auto-detects Meshy or Tripo from the URL.
• Everything in one folder: modelo.glb, PBR textures, preview images, input image and a metadata.json (name, author, prompt, hashes).
• Pretty and friendly: interactive prompts, live progress, clear errors.
• Works with Brave, Chrome or Edge that you already have installed. Nothing big to download.

Quick start

git clone https://github.com/Hectorajm2001/3d-extractor.git
cd 3d-extractor
npm install

Run it with no arguments for the interactive flow:

npm start

Or pass a link directly:

npm start -- "https://www.meshy.ai/3d-models/019dd323-03a2-77fe-915e-239595f2e69b"
npm start -- "https://studio.tripo3d.ai/3d-model/steampunk-airship-with-striped-balloon-wooden-hull-and-metallic-brace-8dce1dae-e552-42cd-9e63-bb068bd04ceb"

Want a global 3dx command? Run npm link once, then just 3dx <url>.

Options

Flag	What it does
-o, --out <dir>	Output folder (default ./models)
-m, --mode <mode>	Tripo only: payload (default), network, or gpu
--no-textures	Skip PBR texture maps
--no-preview	Skip preview images
--show-browser	Show the browser window (helps if headless fails)
--browser <path>	Point to a specific Brave / Chrome / Edge
3dx verify <file.glb>	Inspect a GLB: triangles, skins, animations, materials, textures

What you get

models/<id>/
├── modelo.glb        the model
├── metadata.json     name, author, prompt, SHA-256, signature expiry
├── preview.webp      official preview
├── texturas/         PBR maps (color, normal, roughness, metallic)
└── animaciones/      Tripo retargeting clips (optional)

Open the GLB in Blender, three.js, Godot, Unity, or gltf-viewer.donmccurdy.com.

Tripo modes

Mode	Best for	Keeps rig?
payload (default)	Fast, full quality	Yes
network	When the payload has no URL; grabs what the viewer downloads	Yes
gpu	Last resort; rebuilds the mesh from WebGL	No (static)

Requirements

• Node.js 20+
• Brave, Chrome or Edge (auto-detected on Windows, macOS and Linux)
• Internet connection

How it works

• Meshy serves a proprietary .meshy container that its viewer decrypts in the browser. 3dx runs that same worker inside meshy.ai and streams the resulting GLB to disk.
• Tripo server-renders the page and exposes a signed GLB URL in its Nuxt payload. 3dx reads it; if missing, it can intercept the viewer's download or capture WebGL buffers with WebGLRipper (MIT).

Each engine also works standalone, see meshy-extractor and tripo-extractor (their READMEs are in Spanish).

Responsible use

Use 3dx only on models you own or have explicit permission to use. It retrieves assets the viewers already send to your browser; it does not make a private model free or replace a license. Respect Meshy's and Tripo's terms and the creators' copyright.
