블렌더 json 내보내기; "animation"missing

Question

나는 three.js로 기본 애니메이션을 내보내고 사용하는 방법을 알아 내려고합니다. 믹서기에서 지오메트리를 만들고이를 JSON으로 내 보냅니다. 내가 three.js v 69를 사용하고 있기 때문에 THREE.animationHandler의 사용은 권장되지 않습니다. 라이브러리의 버전에 대한 작동 예제를 찾았지만 여기서는 three.js 라이브러리와 함께 제공되는 예제와 함께 제공되는 JSON에서만 작동합니다 (http://threejs.org/examples/models/skinned/knight.js). MY JSON 파일에이 오류가 출력됩니다 : TypeError: a is undefined three.min.js:682.

파일 사이에 구문 차이가 없습니다.

var loader = new THREE.JSONLoader(), 
    animatedMesh; 

loader.load('./123.json', function (geometry, materials) { 
    var originalMaterial = materials[ 0 ]; 
    originalMaterial.skinning = true; 
    animatedMesh = new THREE.SkinnedMesh(geometry, originalMaterial); 
    // Instantiate the animation 
    var animation = new THREE.Animation(
     animatedMesh, 
     geometry.animation 
    ); 
    animation.play(); 

}); 
scene.add(animatedMesh); 

나는 geometry.animation [0] 로더가 내 JSON을 사용할 때 제공 및 오류, 호출 기능에 첫번째 .hierarchy.lenght 확인합니다. knight.js를 사용할 때 올바른 수의 애니메이션을 얻습니다. 80

내가 테스트를 위해 내 보낸 JSON :

그것은 내 실수를했다

Answer 1

, JSON에 대한 권리 수출을 할 블렌더에서 특정 조건이 있습니다. 또한 일부 모델에서는 해당 애니메이션이 내 애니메이션에 포함됩니다. 올바른 코드는 다음과 같습니다. var animation = new THREE.Animation (animatedMesh, geometry.animations [0]);
