2 years ago hi, 不同模型的骨骼结构是不一样的，骨骼名称也是不一样的。本扩展只能用于Daz和CC3模型。
从你描述的内容看，你需要学习很多的东西，才能自己搞定这个事情。
Blender有个免费扩展，叫：Blender Animation Retargeting https://github.com/Mwni/blender-animation-retargeting
你可以尝试用这个工具转换。
需要注意的是，mmd的动作数据，有很多独特设置，直接映射骨骼名字，并不总是能完美转换。但是，在不写程序的情况下，这个方法算是比较方便的，需要学习的东西也很少。

2 years ago 你好，感谢耐心解答~ 我的FBX模型是niconico上用于VRChat的，骨骼结构会有些不同，不过我想应该差别不大。
好的，我试一下您说的免费插件，只要能转换成标准的FBX/DAE等类型的动画文件就可以了。
另外还想请教一下，您所说的MMD动作数据的独特设置，有什么例子吗？我只要主要骨骼的关键帧数据就好，表情之类的没有也没关系。我的代码里读到的模型骨骼名字，差不多是下面这样的，可能会和VMD的骨骼名字差别很大，您知道有什么工具可以更改动画中的骨骼名吗？我用的是自己的引擎，骨骼名只要能大致转换就可以了，少数实在无法匹配的，我可以hardcode一下字符串。

比如：center和groove骨骼
再然后，它有3个肩膀骨骼：肩，肩P，肩C。
类似这种奇特的现象非常多。因此一对一的骨骼映射，并不总是能得到完美转换。
修改骨骼名称请自行学习Blender。
另外，骨骼映射的方式，是没有表情的。

2 years ago 感谢解答！原来如此，看来是对模型与动画的匹配有特定要求，我再仔细研究一下，many thanks~

作者你好，我不知道Daz和CC3是什么，不过想咨询一下，这个插件是否支持将VMD转换为FBX/DAE，或者retarget到普通的FBX模型上呢？我有个FBX模型，想把Natsumi San的几个动画应用到这个模型上去，但是Assimp在C++端无法读取VMD文件，除了MMD以外目前的主流引擎Unity、虚幻和Godot都处理不了VMD，请问Blender配合这个插件可行吗？只要能把VMD动画数据bake到模型里面，再从Blender导出成glTF/DAE/FBX任何一个模式，我都可以处理。
