1 month ago It should be possible with a script, but I have never successfully gotten it to work. The best I've got so far is pasted below:

My current workflow is to use plugins to import into KKBP bones, simplify armature preparation for Unity, bake light color textures, and export FBX file. Next, I need to open Unity,import FBX , fix the material, change the Animation Type of the rig to Humanoid, export the vrm file using UniVRM-0.57.1, finally convert it to pmx format using VRM2PmxConverter, and Re-import it into Blender.
The reason why I operate this way is that the file processed through the above process,the pmx model file can perfectly apply VMD format animation files directly. Although KKBP supports turning it into a rigify bone during import, this rigify bone cannot be modified into a VMD animation compatible bone through the mmdtool plugin(https://github.com/UuuNyaa/blender_mmd_uuunyaa_tools). Using other Retarget plugins can lead to more or less problems and lengthy workflows.
So...Is it possible to convert KKBP bones to MMD bones directly using this plugin? Perhaps it is also possible to use scripts in Blender to restore the process of bone transformation in Unity?
