2dx3.6使用3d动画的时候动画的那个面不见了

Cocos2d-x
#1

11.c3b是一个直升机动画，它有螺旋桨，代码如下：
_Model = Sprite3D::createFromObjFileAndTexture(“11.c3b”,“playerv002_256.png”);

if(_Model){

    _Model->setScale(0.2);

    auto s = Director::getInstance()->getWinSize();


_Model->setRotation3D(Vec3(90,0,180));



    _Model->setPosition(Vec2(s.width / 2.f, s.height / 2.f));

    this->addChild(_Model);

    

    cocos2d::Animate3D*        m_Swim;

    //受伤的动作

    cocos2d::Animate3D*        m_Hurt;

    //获取骨骼动画信息

    auto animation = Animation3D::create("11.c3b");

    if (animation)

    {
        m_Swim = Animate3D::create(animation, 0.f, 3.0f);

        m_Swim->retain();

        Sequence*    pSequence = Sequence::create(m_Swim,NULL);

        _Model->runAction(RepeatForever::create(pSequence));

    }

当执行动画的时候就螺旋桨就不知道跑那里去了，我不知道是不是世界坐标的问题，有没有大神帮研究一下 11.zip (631 KB)
