Convert GLB into VRM
Avaturn exports in GLTF 2.0
format as it is designed to make sure the 3D model looks well in every engine that uses it.
But VR applications and VTubing software uses "VRM" file format for handling 3D humanoid avatar (3D model) data.
It is based on glTF2.0, so VRM
can be opened by GLTF 2.0
-compatible software, but not vice versa.
