Tools for people who make things move — a 3D animation studio, a viewer for virtual worlds, and a way to prove who made what.
AI can generate motion in seconds. It can't tell you which parts are wrong.
Kinetiq is the studio where raw motion becomes something you'd actually ship. It runs in your browser — no install, no plugins — and your model stays on your machine.
| 🎥 Motion capture from video | Record or upload, and get body, hands and fingers back. |
| 🦴 Auto-Rig | Drop in a mesh, get a working character. |
| 🔁 Retarget Studio | Move animation between skeletons — Second Life Bento, Unreal Engine 5, Unity, Blender, Daz, VRM, Mixamo and more. |
| 😀 Bento Alive™ | A face expression studio built for Second Life. |
| 🧊 Kinetiq Blockout™ | Turn a photo into an editable 3D base mesh. |
| ⚖️ Physics & Polish | Foot locking, joint limits, center of mass, jiggle bones, loop fixing — and a quality score that tells you what still looks off. |
| 📦 Export | .fbx, .glb, .bvh, and .anim for Second Life. |
The Second Life® viewer, rebuilt from scratch.
Viewers grew heavier every year. We started over and asked a simpler question: what if getting into the world felt weightless again?
- Featherweight — under 25 MB to install, and roughly 4× lighter in memory than legacy viewers.
- A from-scratch graphics engine — real shadows, a sun that crosses a full day, and local lights that make a build glow after dark.
- Built to fit any machine — adaptive rendering that scales to what you actually have, plus free frame rate from AMD FidelityFX™ Super Resolution on any GPU.
- Faces that come alive — real-time facial animation, built in.
- Translation that never leaves your machine — chat translation across nine languages runs locally on your own computer, not on a server. Built on Bergamot / Firefox Translations (Mozilla), MPL-2.0.
- Private by construction — it runs on your machine. Your login goes only to Linden Lab, never to Thirdrez. No relay servers.
- Creator tools where you already are — Kinetiq Engine, Bento Alive™ and Trezz Share are built into the viewer.
Free to download and free to use. Windows first; macOS and Linux to follow.
Proof of authorship, sealed into the file itself.
MotionPrint™ signs an animation with Ed25519 and SHA-256, embedding unforgeable proof of authorship in the file's metadata — the motion data itself is never touched.
- Verified client-side. Files are checked in your browser and never stored on a server.
- No account, no cost. Anyone can verify a file, including people who don't use our tools.
- Non-destructive. The signature lives in metadata, so nothing about the animation changes.
- Works in GLB, glTF and BVH.
