Welcome to Thirdrez Documentation
Thirdrez is a next-generation ecosystem for 3D motion synthesis, provenance, and distribution. We bridge the gap between high-fidelity animation and ethical AI through two core technologies: Kinetiq Engine and MotionPrint Protocol.
Mirror Animation is free for every tier with live scrub, viewport projector, and bone-pair highlight. Loop Fixer, Quality Score, Foot Locking, Joint Limits, Center of Mass, and Jiggle Bones all ship in 1.0 — and v1.1 "Refine & Precision" (June 11, 2026) adds Smooth, Trajectory View, Range tools, a complete Foot Locking rebuild with Bake to Timeline, and FBX export. See What's New for the full overview.
Kinetiq Engine
Kinetiq is a browser-native animation engine for production-ready 3D motion. It combines a polished editing surface (timeline, IK, keyframes, retarget) with biomechanics-grade tools (foot locking, quality score, joint limits, center of mass) and AI-assisted capture (webcam + video mocap via Vision Capture).
Key Features today (production):
- Browser-native — runs in Chrome/Firefox/Safari with no installation, powered by Three.js + WebAssembly
- Multi-platform import — Second Life Bento (159 bones), Unity Humanoid (54), UE5 Mannequin (67), Roblox R15/R6, Mixamo, generic GLB/FBX
- Multi-platform export — FBX (binary 7.4, client-side, per-DCC presets), GLB, BVH, and SL
.animfor Second Life direct upload - AI-assisted mocap — Vision Capture for webcam + video pose extraction
- Professional physics suite — Foot Locking (bake-able), Quality Score, Joint Limits, Center of Mass, Jiggle Bones (bake-able)
- Polish suite — Mirror Animation (free), Smooth, Simplify Keyframes, Range, Loop Fixer, Trajectory View
In active training (post-launch demos):
- Amanda Co-Pilot — generative motion model (MDM/LoRA) being trained in-house. See the Amanda Co-Pilot page for the roadmap.

MotionPrint Protocol
MotionPrint is our open cryptographic provenance protocol. It ensures that every animation generated or distributed via Thirdrez carries a permanent, non-destructive "digital fingerprint."
Key Features:
- Privacy-First: All signing and verification happen client-side via WebAssembly. Your files never leave your machine for verification
- Trustless: Uses Ed25519 digital signatures to guarantee authorship
- Format Agnostic: Seamless integration with GLB/glTF and BVH metadata
