| 修改导出的动画多一 frame的bug | |
| 2015-2-5 支持批量导入一个文件夹 某个 模型 所有的 动画 导出为 fbx模型 | |
| [已知BUG: ratman 和 主城第一个npc 的idle 动画导出存在旋转问题， ratman的背包的旋转方向反了，npc的手臂旋转方向反了] | |
| 注意::下面 代码 函数 fileselection_callback 使用了macos 上面的file 命令用于 识别文件格式 是否是UTF-16, 如果在windows上面使用需要 替换为windows命令，或者保证 转化生成的xml 文件为UTF-8 编码去掉文件编码检测也可以 | |
| 测试::测试了火炬之光 1中的 media/models/warrior/player.mesh 战士 主角的模型 动画导出 | |
| 0: 将脚本 放到 blender的插件目录中 | |
| 1：打开一个空场景 去掉 场景中 所有物体 和 相机 以及其它任何东西 | |
| 2：file import ogre 打开某个目录的 mesh文件 | |
| 3：导入后 将会 自动生成 这个 模型的 所有动画的 fbx 在 模型目录下面 | |
