MotionCraft

MotionCraft is an RL-based motion generation model for game developers. Instead of hand-crafted animations, keyframes, or motion capture, the model generates character movement in real time, directly inside Unreal Engine 5. The model is already trained and runs locally on your machine. No cloud dependency, no latency. Clone the repo, run the demo, and see a skeleton character moving through a level with zero animation assets. Every step, turn, and reaction to the environment comes from the model output. This is an early MVP. Current capabilities are intentionally limited: forward locomotion and turning, a specific skeleton, Windows 11 and NVIDIA GPU required. We're sharing it now because we want feedback from developers who've hit the animation wall, solo devs building 3D games without the budget for a motion pipeline, small teams that want to prototype movement without rebuilding state machines every time the design changes. The long-term goal is characters that handle complex terrain, react to obstacles, and move naturally all from a model, with no animation pipeline involved. This is the first public step. Free to use. Custom builds available for specific projects.
