Procedural Legs for a Real-Time Avatar - Unity IK Expert Needed (VRM, Quest)

About the project We're building a real-time avatar application: a person's movements, captured via a Meta Quest headset and controllers, drive a VRM avatar live, which other users see updating in real time on a separate companion app. What we need Our rig uses UniVRM + Final IK (VRIK) - head/hands track the headset and controllers, legs run on VRIK's procedural locomotion. It works, but walking doesn't look natural yet. We need someone who can tune and extend the lower-body system so it holds up against the tracked upper body, with a seamless blend between the two. Open to better IK tuning, custom procedural work, or ML-driven locomotion if you think it's the better path. Stack Unity, OpenXR/XRI, UniVRM, Final IK/VRIK, a real-time networking layer for syncing avatar movement, ARKit/ARCore on mobile. Requirements Strong experience with procedural IK and humanoid rigging in Unity Hands-on experience with Final IK/VRIK or equivalent full-body VR IK (e.g. VRChat-style 3-point tracking) Comfortable with VRM avatars and Unity's Humanoid rig General Unity XR / Quest development experience Nice to have Procedural locomotion or motion-matching experience; real-time networked avatar sync experience; AR mobile dev experience. Equipment for testing Meta Quest headset (2/3/Pro) and an iPhone 14+. Engagement Likely ongoing, scope/hours open to discussion based on fit. Please include relevant IK/locomotion work examples when applying.
