Android Rajawali正在加载.FBX文件

我下载了最新的Rajawali示例。我已尝试加载从internet下载的.FBX文件

将文件放入原始目录（从此处下载）

我的班级在这里

   try {
        LoaderFBX parser = new LoaderFBX(this,
                R.raw.wolf_fbx);
        parser.parse();
        Object3D o = parser.getParsedObject();
        o.setY(-.5f);
        getCurrentScene().addChild(o);
    } catch (ParsingException e) {
        e.printStackTrace();
    }

此代码引发java.util.EmptyStackException

有什么想法吗？

我也有同样的问题。我正在加载FBX文件。
