Fix a broken Meshy AI rig

Exploded mesh, stretched limbs, frozen T-pose or jittery animation from Meshy AI? Here is the two-minute browser fix.

Meshy AI's auto-rigging is impressive, but exported .glb and .fbx files sometimes arrive with a broken bind pose (the "exploded polygon" look), wrong scale, inverted normals or noisy skin weights. You do not need Blender to fix any of these — Rig Bake repairs them automatically on import, free and without uploading your model anywhere.

How to do it

  1. Import the file. Open rigbake.com and drag your Meshy AI .glb or .fbx into the window. The Model Doctor analyzes it in a background worker and lists every problem it finds.
  2. Apply the suggested fixes. Typical Meshy findings: broken bind pose (rebind skeleton), duplicate vertices (weld), wrong unit scale (normalize), and skin-weight cleanup. Each fix is opt-in — tick the ones you want and apply.
  3. Check the animation. Press play. If clips came from another source, use animation retargeting with automatic bone mapping. Crop or de-jitter clips on the timeline if needed.
  4. Export. Download the repaired model as .glb (free), bake a spritesheet for a 2D game, or export STL for 3D printing.

What each Meshy symptom means

  • Exploded / spiky mesh — corrupt inverse-bind matrices. Fix: rebind skeleton (automatic).
  • Model is tiny or gigantic — centimeter/meter unit mismatch. Fix: scale normalization.
  • Model looks inside-out or invisible from the front — inverted normals. Fix: flip winding + normals.
  • Candy-wrapper twisting at wrists and shoulders — noisy auto-rig weights. Fix: skin-weight cleanup.
  • Animation vibrates or stutters — redundant/noisy keyframes. Fix: the clip "Clean up" operation.

Frequently asked questions

Is this really free?

Yes. Import, repair, animation editing and .glb re-export are free with no account. Pro only raises spritesheet baking limits.

Does my Meshy model get uploaded?

No — everything runs locally in your browser via WebGL 2. The file never leaves your machine.

Can I put Mixamo animations on my fixed Meshy character?

Yes — import the Mixamo .fbx alongside it and Rig Bake auto-maps the mixamorig bones onto your character's skeleton.
