VRoid Hub is a platform to upload (human) 3D model data created with software such as VRoid Studio. Characters registered to VRoid Hub can be imported and used as avatars on other VR/AR platforms and 3D contents by using the dedicated SDK.
After a 3D character is uploaded to VRoid Hub, an individual profile page will be created for that character. There, users can browse the character's name, various social media and other information. If the creator allows it, the model data can also be downloaded.
The model data on VRoid Hub can be used with various 3D services such as VR/AR platforms supporting that model data of the VRM format and games created with Unity.
