从Blender批量导出OGRE模型骨骼动画

导出插件设置

从Blender导出OGRE模型

Blender 运行 Python 脚本

打开控制台输出

移动鼠标到箭头所指左下角, 当鼠标变为十字时候按住并往上拉

选择文本编辑器

新建文件, 打开代码提示, 就可以写代码了

批量导入FBX导出OGRE骨骼动画脚本

导出的动画名字默认为 my_animation

同个骨架内的子网格所带的骨骼和动画都一样, 即skeleton文件相同(请验证)

导出很多无用文件, 未进行删除(只保证skeleton文件正确)

动画过长的情况, 请调整模型骨骼动画去除空帧或手动导出

导出动画骨骼文件(skeleton)以fbx文件名命名
