Saves skin weights to a portable JSON file and loads them back: in place, or transferred by closest point onto a rebuilt mesh.
What it does
Weights to JSON, back two ways
Skin IO saves a mesh's skin weights to a JSON file and loads them back. A load can be scoped to selected vertices to patch one area. It ships as popover shortcuts on a fixed temp file, plus a full window with Save and Load tabs.
Loads weights straight back onto the same mesh, vertex for vertex.
Transfers weights by closest point onto a rebuilt mesh; different topology is fine.
Quick start
Save, then load, Direct or Transfer
- 1
Open the Skin popover on the Bridge toolbar and click "Skin IO Window…" (or the Maya menu entry).
- 2
On SAVE, select your mesh, click Use Selected, confirm the output path, and click Save Skin Weights.
- 3
On LOAD, select the target mesh, click Use Selected, and set Skin File to the saved JSON.
- 4
Pick Direct or Transfer, then click Load Skin Weights.
Direct checks count, not order
Direct mode only checks vertex count, not order. Use Transfer whenever the mesh was rebuilt, even if the count matches.
Single target for Direct & scoped
Direct mode and vertex-scoped loads need a single target mesh; use Transfer for multiple meshes.
Missing influences skipped by default
"Create missing influences" is off by default, so missing joints are silently skipped unless you turn it on.
