VGO import - izayoijiichan/VGO GitHub Wiki
Prepare a VGO file (.vgo).
Initial import using UniVGO is not possible.
You need to prepare a file of a file format (.fbx, .dae, .3ds, .dxf, .obj, .blender, .max, etc..) that Unity supports Humanoid import.
Import the file using Unity's functionality.
At this time, Rig must be set correctly.
Place the VGO file anywhere under Assets.
If an error has occurred, the Console will display the details of the error.
If there are no errors, the import is complete.
You can place the object by selecting the VGO file from the Project window (tab) of the Unity Editor and dropping it on the Hierarchy.
Locate the VGO file in the Unity Editor's Project window (tab) and select it.

The Vgo Scripted Importer is displayed in the Inspector window (tab).
Click the Extract button of Material and Textures to start extracting textures and materials.
The extraction is confirmed by clicking the Apply button.
