The models created with VRoid Studio Stable Ver. can be used for commercial purposes.
When you use VRoid Studio Stable Ver. to create your own avatars, textures, etc, pixiv wants you to be able to use your creations freely for all kinds of purposes.
Even with regards to other data that pixiv may hold the rights to, the VRoid Studio Terms of Use are fundamentally written to be broad and account for a wide variety of purposes and uses. You can sell data and use it for commercial purposes, regardless of whether you're an individual or corporate body.
Please read through the following carefully and keep your usage in line with what's detailed.
① When using the work of other creators
As an example, if you're using data that another creator holds the rights to, such as textures you've purchased, you will need to abide by that data's license and conditions of use.
pixiv not only respects your individual rights as a creator, but also respects the rights of other creators.
② When using data that has a special clause written in the license
Because VRoid Studio Stable Ver. is an intuitive program with plenty of expressive power in character making, it boasts a wide variety of items. It's possible that there are some items offered with usage restrictions.
If you see special licensing terms in VRoid Studio Stable Ver., please observe those specific terms. Even when using a sample model or included textures, please refer to the sample model's conditions of use.
Outside of situations when other special licensing terms are displayed, you can sell data and use it for commercial purposes, regardless of whether you're an individual or corporate body. For more details, please refer to Article 11 of VRoid Studio Terms of Use.
③ When creating character making tools
You cannot create an application that can generate or output 3D models, avatars, or items consisting of deformed or combined meshes and textures that were created in VRoid Studio.
If you'd like to create an application with these sorts of functions, it is necessary for you to accept a separate license from pixiv. However, if a program of this nature is only intended for use by you yourself, then this restriction is not in place.
Please contact us if you'd like an application creation license. It's possible that we may decline granting you a license. Thank you for your understanding.
For more details, please refer to the VRoid Studio Guidelines or the VRoid Studio Terms of Use.
