What is VRM?

VRM is an open file format for 3D humanoid avatar models, built on top of the glTF (GLB) 3D standard. A single .vrm file bundles the 3D model, textures, skeleton/rigging, and facial blendshapes, making it portable across VTuber apps, VR, and metaverse platforms.

VRM was created to solve a simple problem: 3D avatars made in one app often wouldn't work in another. By standardizing how a humanoid model is structured — its bones, its facial expressions, its look-at behavior — VRM lets the same avatar load into many different applications without conversion. It is maintained by the VRM Consortium and is widely used across the VTubing community.

Because VRM extends glTF (the open 3D format whose binary form is GLB), a VRM file carries everything an app needs in one place: geometry, materials and textures, a humanoid bone hierarchy, and blendshapes (also called BlendShapeProxy) that drive facial expressions and lip-sync. That's why VTuber software can load a .vrm and immediately track your face onto it.

For VTubers, VRM is the practical default for 3D avatars. Apps like VSeeFace, Warudo, 3tene, VNyan, VMagicMirror, and Animaze all load VRM files directly. VTubeMe exports a standard .vrm (plus a GLB) from a single selfie, so your avatar works in all of them without extra steps.

VRM — FAQ

What does VRM stand for?
VRM isn't a conventional acronym — it's the name of an open file format for 3D humanoid avatars, built on the glTF 3D standard and maintained by the VRM Consortium.
What apps use VRM files?
Most VTuber software supports VRM, including VSeeFace, 3tene, Warudo, VNyan, VMagicMirror, and Animaze. VRM is also used in VR and metaverse platforms.
How do I get a VRM avatar?
You can build one manually in VRoid Studio, commission an artist, or generate one automatically from a selfie with a tool like VTubeMe, which exports a standard .vrm file in minutes.
Is VRM the same as GLB?
No, but they're related. VRM is built on top of glTF, whose binary form is GLB. VRM adds avatar-specific data (humanoid bones, blendshapes, look-at) on top of a GLB-style model. Every VTubeMe download includes both a VRM and a GLB.
