Let's use motion capture
 Here, I'll be explaining how to apply BVH files, which are external motion data files, to the model, in addition to how to combine them with keyframe motion.
  In the first section, I will explain up until applying BVH files to a model. It was not explained in this video, but the BVH files that I am using have been provided by the Carnegie Mellon University in the United States.
 When creating BVH files yourself, I recommend that you use an armature of similar composition to that provided by Carnegie Mellon University.
 
 
 
In the second section, I will explain how to combine keyframe motion on a model on which the file's motion has been applied.
 With pastel action, you can separate the adding of Euler rotation keys and Quaternion rotation keys for each bone in order to combine the motion.
