Fix a Rodin AI model
Weld, de-noise and repair Rodin / Hyper3D exports so they behave in game engines, renderers and slicers.

Rodin (Hyper3D) produces unusually detailed meshes, and the cleanup they need is geometric rather than structural — the shape is right, the topology describing it is not. Four things recur. Vertices are split into duplicates along every UV seam, so the mesh is not connected topology and no operation that walks from one triangle to its neighbour can work. Small fragments float inside or beside the surface. Boundary loops sit open where two surfaces failed to meet. And a handful of faces are wound inward, making the model read as hollow from one angle.
None of these show up in a render, which is why they surface three steps later — at an unwrap, a boolean, a bake or a slicer. Rig Bake counts each one on import (how many duplicates, how many fragments, how many open edges) and fixes them in the order that actually works: welding first, because until the duplicates are collapsed the other three questions cannot be asked correctly. Textures are untouched — the weld is UV-aware, so seams survive rather than being averaged away.
How to do it
- Import and read the report. Drag the Rodin .glb into rigbake.com. The analysis lists duplicate vertices, degenerate triangles, disconnected pieces, tiny islands and open edges for the file.
- Apply geometry fixes. Weld duplicates (UV-seam aware — textures survive), remove tiny islands, optionally close holes, and flip normals if the mesh reads inside-out.
- Optional: reduce or repurpose. Generate a LOD chain for game use, export a posed STL for printing with a watertight report, or bake the model into 2D spritesheets.
Texture-safe cleanup
Rig Bake preserves the original encoded texture bytes from the GLB, so repairing geometry and re-exporting does not re-encode your JPEG/PNG/WebP maps — no quality loss and no cracked seams on normal maps.
Frequently asked questions
Will welding vertices ruin my UV seams?
No — the weld is position, UV and normal aware, so it only merges true duplicates and leaves intentional seams alone.
Can I 3D print a Rodin model?
Yes. After cleanup, the STL exporter scales to millimeters, orients Z-up and reports whether the mesh is watertight before you download.
Is anything uploaded to a server?
No — analysis and repair run entirely in your browser.
