Split3r depends entirely on the quality of your files
Auto-selection works by analyzing the geometry and topology of your mesh. If the mesh is dirty (non-manifold edges, holes, flipped normals, self-intersections, distorted geometry), the analysis will struggle, and your cuts or extractions can fail or crash. That is why Split3r ships with a full set of tools to analyze, simplify and repair your files, and to fill and clean automatic selections before you extract. These steps are not optional decoration, they are part of the workflow. Skip them on a problematic file, and you should expect problems.
It is not magic, it is mathematics
Auto-selection and one-click extraction rely on real geometry and topology analysis, not guesswork. There are billions of files on the web, plus an endless stream generated by AI, and no geometric algorithm can correctly separate every possible shape on the first click. These commands are genuinely innovative and have only existed since the end of April 2026. Expecting them to flawlessly extract every part of every file in the world is unrealistic. They won’t, not yet, and possibly not ever for the worst inputs.
Read the Getting Started first
