This is a video showing Mixamo motions and characters in a forest.  The ronin is from The Alive guy Instructor - Pierrick Picaut free to download here.    I wasn't sure how to get his excellently rigged character to receive the mocap, so i think I deleted the armature, used the mixamo website's auto rigger, and used the one of the running animations.  I also used several already mocaped characters and animations from mixamo website.  I added some running sounds.
