Metrixel — Motion Generation, Motion Retargeting & 3D Asset Preparation

Creating character animation and preparing 3D assets can both demand specialized tools and repetitive work. Independent creators need practical ways to animate their characters, while AI/ML teams often start with thousands of locally collected FBX, GLTF/GLB, and OBJ assets. Precious time is lost to formatting quirks, inconsistent transformations, one-off render scripts, and preprocessing pipelines that nobody can reproduce months later.

Metrixel™ brings character motion workflows and reproducible 3D dataset preparation into one desktop tool: it converts locally available FBX, GLTF/GLB, and OBJ assets into consistent, AI-ready dataset outputs. It can also provide turntable and multi-view renders, PyTorch .pt mesh tensors, extracted textures, USD (USDA) animations, signed-distance-field (SDF) voxel grids, and a JSON manifest that links every output back to its source asset.

For creators, Metrixel supports character-motion workflows; for studios and AI/ML teams, it makes local asset preparation repeatable and organized. It does not download datasets or train customer models — its dataset tools prepare assets for downstream production and training.

Without Metrixel	With Metrixel
Hand-written import scripts per formats.	One pipeline for FBX, GLTF/GLB, and OBJ.
Per-asset manual render setup.	Deterministic camera, lighting, and framing for every asset.
Custom mesh-to-tensor conversion codes.	PyTorch .pt export out of the box.
"How exactly did we generate this dataset long ago?"	Same configuration → same outputs, GUI or headless CLI.

For animated datasets, Motion Retargeting applies one motion library to every character — sources in FBX, GLTF/GLB, or BVH — and Mesh-Aware Correction reduces the self-penetration that retargeting onto a differently-shaped character can cause, such as an arm passing through the torso.

New in 2026.3.2 — Motion Generation (Experimental AI feature, Standard and Professional plans)

Describe the motion you need in plain English — "Walk for 10 seconds, turn left, then jog for 8 seconds and wave with the right hand for the last 3 seconds" — and Metrixel builds it as an animation clip on its built-in character, ready to preview, refine with a follow-up request such as "Make the run slower", save as GLB, and — on the Professional plan — retarget onto your own rigs. An on-device language model reads your request, Metrixel assembles the motion from a library of openly licensed motion capture and studio-authored gestures, and a learned model generates the in-between frames where one way of moving changes into another, such as walk to run. It all runs on your machine: the models download on demand, and your words stay local unless you choose to send us a motion request.

Experimental means a deliberately small vocabulary that grows release by release: walk, run or jog, turn, stand, jump, wave, and carry a bag, in sequence or at the same time. Ask for anything else and Metrixel tells you it is not supported yet — with a Request this motion… button, so you decide what we add next.

Every Metrixel run can also be configured as a headless command-line pipeline (metrixel --mode cli), suitable for Amazon SageMaker training jobs, CI runners, and SSH-only Linux hosts. Every run writes a JSON manifest so downstream pipelines can ingest results without bespoke parsing.

For free users who are signed in, we provide:

• 1,000 export tokens to evaluate the tool before subscriptions.
• No credit card requirement.
• Low friction signup.
• Clear indication of how much quota. No more being taken by surprise on how much more you can use.
