During an RMB path-follow the body yaw locks to the leg direction (rig commit_body_to_motion, from interpolated velocity — immune to SetFacing interleaving between throttled steps). The mouse instead drives a layered look-at: LookAtModifier3D pair on Head (±70°) + spine_02 (±30° torso twist for looking far lateral/behind — past their sum the character physically cannot look further without turning). Forward axis measured from the armature rest pose (+Z), not guessed. Influence fades in/out on follow start/end. Pure client presentation per D-249; SetFacing still rides the wire, so the server vision cone follows the mouse while walking — the character looks where the player points.
