javascript - ThreeJS动画几何体不更新但位置会更新？

Question

我会先说我是 Blender/3DS MAX/ThreeJS 和图形编程的新手。

我从《星际争霸》编辑器中将飞龙(来自《星际争霸》)拍打翅膀的动画导出为 .m3 文件，然后将其导入到 Blender 中。导出后，我可以将生成的 .json 导入到我的 ES6 应用程序中，但由于某种原因，使用 THREE.Animation，虽然导入的 Mutalisk 的位置正确更改，但它会左右摇摆，而 Mutalisk 对象的实际拍动却不会不会发生。

我的渲染器如下所示:

import THREE from 'three';

export default class Renderer {
  constructor(game, canvas) {
    this.game = game;
    this.canvas = canvas;

    this.scene = new THREE.Scene();

    this.camera = new THREE.PerspectiveCamera(75, this.canvas.width / this.canvas.height, 1, 10000);
    this.camera.position.z = 2;
    this.camera.position.y = 1;

    this.clock = new THREE.Clock;

    this.renderer = new THREE.WebGLRenderer({ canvas: this.canvas });
    this.renderer.setSize( this.canvas.width, this.canvas.height );
  }

  // called by my Game class, which waits for the mesh to load before attempting to add it to the scene
  addMeshToScene(mesh) {
    this.mesh = mesh;

    this.scene.add(this.mesh);

    this.animation = new THREE.Animation(
      this.mesh,
      this.mesh.geometry.animations[ 2 ]
    );

    this.animation.play();
  }

  renderFrame() {
    THREE.AnimationHandler.update(this.clock.getDelta());

    this.renderer.render(this.scene, this.camera);
  }
}

这是渲染图。正如我所说，我的浏览器中的飞龙沿着 Y 轴弹跳，但没有拍打。

谁能解释一下为什么会发生运动而不是拍打？

编辑:这是我的 Blender 导出设置。

已解决。问题是 Material 必须处于蒙皮模式才能正确包裹骨架。当我从 JSON 创建网格时，我必须设置 material.skinning = true

import THREE from 'three';

export default class Mesh {
  constructor(name) {
    this.name = name;
    this.loaded = false;
    this.filepath = `./meshes/${this.name}.json`
    this.load();
  }

  load() {
    var loader = new THREE.JSONLoader();
    loader.load(this.filepath, (geometry) => {
      this.geometry = geometry;
      var material = new THREE.MeshBasicMaterial( { color: 0x00ffff, wireframe: true } );
      material.skinning = true; // this is where the magic happens
      this.mesh = new THREE.SkinnedMesh(geometry, material);
      this.loaded = true;
    });
  }
}
