Motorica

Motorica generates character animations for games and 3D projects using models trained on motion capture data. Animators and game teams use it to get natural locomotion and reactions in seconds, then adjust the result instead of cleaning raw mocap.

You control root motion so the animation matches your gameplay system, and you can direct style to shape the performance of your virtual actor. A studio quoted on the site says the control is deterministic enough to translate cleanly into Unreal.

The company says its data comes from mocap actor performances that were ethically sourced and that its founders pioneered deep learning for 3D animation synthesis. A Lite version is free to try, and demos can be booked for larger studios.
