Open a .cmo3 file without Cubism Editor

Ayatsuri2D opens Live2D Cubism Editor projects (.cmo3) as whole models: the art, meshes, parts, deformer tree, parameters in their folders, every keyform, clipping, blend modes and physics, with the names the rigger gave them. It is free, needs no account, and runs on Windows, macOS and Linux.

Download 0.5.8Rig your first model

How to open one

  1. Download Ayatsuri2D and start it.
  2. Choose File > Open, or drop the .cmo3 on the window.
  3. The model opens ready to rig: select a mesh, move a parameter, edit a keyform.

What you can do with it

  • Keep rigging a model someone else started in Cubism, or one you made on a computer that no longer has the Editor.
  • Export moc3 (3.0 to 5.3) for VTube Studio and other apps built for Cubism models; see VTube Studio.
  • Save it back as .cmo3 with File > Export Model… on the cmo3 tab, to hand it to someone who uses Cubism.
  • Save as .aom, Ayatsuri2D's own open format, which keeps everything in one file.

When it is not a .cmo3

A .moc3 with its .model3.json is the exported model, not the project. Ayatsuri2D opens those too, with their physics, motions and expressions; Cubism Editor itself does not open moc3.

Questions

Can I open a .cmo3 file without Live2D Cubism Editor?

Yes. Ayatsuri2D opens .cmo3 projects for free, with the art, meshes, deformers, parameters, keyforms, clipping and physics, on Windows, macOS and Linux.

Can I edit a .cmo3 and export it for VTube Studio?

Yes. Open it in Ayatsuri2D, change what you need, and export moc3 with File > Export Model… on the moc3 tab. VTube Studio loads the result like any Cubism export.

Can I open a .moc3 file to edit it?

Yes. Ayatsuri2D opens .moc3 bundles with their physics, motions and expressions. Cubism Editor does not open moc3, only its own .cmo3 projects.
