First, I read the FBX file and generated my own file.
var Scenes = new Scene();
var opt = new FbxLoadOptions() { KeepBuiltinGlobalSettings = true };
Scenes.Open(fbxPath, opt);
…... var scenes = new Scene(); var opt = new FbxLoadOptions()...= true }; scenes.Open(fbxPath, opt); Write1S(scenes, SavePath);...
