All live2d animations are handled in data/others/plugin/live2d/driver/index.js (included in live2d.tpatch)
beautify js using https://beautifier.io/, and add the code below to index.js line 3604.
scriptPlayer.playScript(${this._modelSetting.getModelFileName().replace(“.moc3”, “”)}/${n});
I guess the hardest part here is scripting these motion files.
And maybe we need to filter out some models like Doris_Heart, Doris_goddess, Doris_talk.
