API Reference

v1

three-vrm v1 has been released!

three-vrm v1 supports VRM1.0, which is a new version of VRM format (the previous version of VRM is also supported, don't worry!). It also adopts the GLTFLoader plugin system which is a relatively new feature of GLTFLoader.

There are a lot of breaking changes! See the migration guide for more info.

How to Use

from HTML

You will need:

• Three.js build
• GLTFLoader
• A build of @pixiv/three-vrm
  • .module ones are ESM, otherwise it's UMD and injects its modules into global THREE
  • .min ones are minified (for production), otherwise it's not minified and it comes with source maps

Code like this:

<!-- About import maps, see the Three.js official docs: -->
<!-- https://threejs.org/docs/#manual/en/introduction/Installation -->
<script async src="https://unpkg.com/es-module-shims@1.3.6/dist/es-module-shims.js"></script>

<script type="importmap">
  {
    "imports": {
      "three": "https://unpkg.com/three@0.162.0/build/three.module.js",
      "three/addons/": "https://unpkg.com/three@0.162.0/examples/jsm/",
      "@pixiv/three-vrm": "three-vrm.module.js"
    }
  }
</script>

<script type="module">
  import * as THREE from 'three';
  import { GLTFLoader } from 'three/addons/loaders/GLTFLoader.js';
  import { VRMLoaderPlugin } from '@pixiv/three-vrm';

  const scene = new THREE.Scene();

  const loader = new GLTFLoader();

  // Install GLTFLoader plugin
  loader.register((parser) => {
    return new VRMLoaderPlugin(parser);
  });

  loader.load(
    // URL of the VRM you want to load
    '/models/VRM1_Constraint_Twist_Sample.vrm',

    // called when the resource is loaded
    (gltf) => {
      // retrieve a VRM instance from gltf
      const vrm = gltf.userData.vrm;

      // add the loaded vrm to the scene
      scene.add(vrm.scene);

      // deal with vrm features
      console.log(vrm);
    },

    // called while loading is progressing
    (progress) => console.log('Loading model...', 100.0 * (progress.loaded / progress.total), '%'),

    // called when loading has errors
    (error) => console.error(error),
  );
</script>

via npm

Install three and @pixiv/three-vrm :

npm install three @pixiv/three-vrm

Code like this:

import * as THREE from 'three';
import { GLTFLoader } from 'three/examples/jsm/loaders/GLTFLoader';
import { VRMLoaderPlugin } from '@pixiv/three-vrm';

const scene = new THREE.Scene();

const loader = new GLTFLoader();

// Install GLTFLoader plugin
loader.register((parser) => {
  return new VRMLoaderPlugin(parser);
});

loader.load(
  // URL of the VRM you want to load
  '/models/VRM1_Constraint_Twist_Sample.vrm',

  // called when the resource is loaded
  (gltf) => {
    // retrieve a VRM instance from gltf
    const vrm = gltf.userData.vrm;

    // add the loaded vrm to the scene
    scene.add(vrm.scene);

    // deal with vrm features
    console.log(vrm);
  },

  // called while loading is progressing
  (progress) => console.log('Loading model...', 100.0 * (progress.loaded / progress.total), '%'),
