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 now free for every tier with live scrub, viewport projector, A/B compare, and bone-pair highlight. Loop Fixer, Quality Score, Foot Locking, Joint Limits, Center of Mass, and Jiggle Bones all ship in 1.0. 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 — GLB and BVH today; SL
.animfor Second Life direct upload; FBX coming Q2 2026 - AI-assisted mocap — Vision Capture (BETA) for webcam + video pose extraction
- Professional physics suite — Foot Locking, Quality Score, Joint Limits, Center of Mass, Jiggle Bones
- Polish suite — Mirror Animation (free), Loop Fixer (paid)
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
