Here I document how I added animations to this 3D model from Mixamo with animations pulled from Annie’s live Mocap recording. I imported the 3D model files and extracted the models embedded textures and materials. I set the models rig type to humanoid. I imported the animation files and also set their rig type to humanoid.
Then I created a new animation controller, added a new state and assigned the animation file to the state. Then I assigned this controller to the models animation controller input.
Then all I had to do was position the camera correctly and hit the play button, and the model began moving. Here is a screenshot from the model in motion.
