> Talos next · Since 0.6; changed in 0.7

One foot: the IK chain it drives, its end bone, and where it sits in the character's own frame.

## Signature

```ts
export interface FootProp {
  /** The animator's `ik` chain this foot drives. */
  chain: string
  /**
   * Where the ray goes when the foot's bone cannot be read, in the character's own frame:
   * beside the hips, so the foot is planted there whatever the clip is doing.
   */
  offset: Vec3
  /**
   * The chain's end bone. While the rig has it, the foot is planted where the clip puts it
   * (its pose before IK) and only moved up or down with the ground, so a walk keeps its
   * stride and its swing. Default `LeftFoot` / `RightFoot` for the default chains.
