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.
