What is Live2D Cubism?
Live2D Cubism is the professional authoring toolchain for 2D VTuber art. Illustrators split characters into layers; riggers bind meshes, physics, and parameters in Cubism Editor, then export a puppet that trackers such as VTube Studio can load.
Cubism is not what viewers see on stream—it is what artists and riggers use before the first live test.
Authoring vs performance
Think of Cubism as the shop and VTube Studio as the stage. Performers with store-bought Live2D often never open Cubism. You need Cubism when you commission custom art, edit an existing rig, or build models as a career skill.
Outputs trackers expect
Exports land as .model3.json projects with texture folders. Those bundles import into VTube Studio for face tracking. Cubism does not produce VRM 3D avatars—that pipeline lives in VRoid and 3D trackers instead.
Who Cubism is for
Cubism fits artists, riggers, and studios producing Live2D at scale. It is optional for streamers who only purchase finished models with streaming rights.
