KitSplit

Split messy kitbash and multi-material meshes into clean, named, export-ready pieces in one click.

You know the drill: join a kitbash, then spend forever separating materials, renaming Cube.003, fixing origins, making collections, and exporting GLBs — only to realize the origins were wrong.

KitSplit does that loop in one click.

1. Select your mesh

2. Open the KitSplit sidebar tab

3. Choose By Material, By Loose Parts, or By UV Island

4. Click Split

5. Optionally Export Pieces as GLB
