Process & Details

Blueprint Node Overview
This procedural animation system is built in Unreal. Instead of using keyframe animation, everything is calculated in real time with Blueprints. The system takes the character’s foot bones and root bone as inputs, then figures out where the feet should go based on the character’s speed and a sphere trace. After that, it snaps the feet to the right spot. I also added some extra details, like a bit of head sway and some shoulder rotation.
Surface traces let the feet find contact points on the ground and nearby objects.
