VRoid Hub's license fields turn a model upload into a legal choice

The setup

VRoid Hub is pixiv's official platform for publishing avatars made in VRoid Studio so others can view, license and reuse them. Publishing is not just an upload: pixiv's help center documents a dedicated usage-conditions settings screen, set once per VRM file at export or upload. This screen, not one platform-wide rule, governs what anyone else may do with a specific model once it is public.

What the documents show

The settings screen splits permission into two groups. The first controls who can perform as the avatar: 'only the author,' 'only the explicitly permitted entities' or 'anyone' may use the model to deliver third-party voices or actions, with separate toggles for violent expression, sexual expression and commercial usage. The second controls redistribution and modification through Creative Commons options, from a full copyright waiver through CC BY, CC BY-NC, CC BY-SA and their no-derivatives variants, or 'redistribution prohibited' with no CC license. A companion article on commercial use on VRoid Hub defines commercial use broadly, as any exchange of money or indirect monetization such as advertising, and tells users to contact a model's author directly, since Hub has no built-in messaging. VRoid Hub's own content guidelines, retrieved via an archived snapshot, list 'violating the scope of authorizations/licenses and terms of use stipulated by 3D model creators' as prohibited, and note a model's VRM metadata can carry contact details, which pixiv strips of personal fields such as phone numbers or emails on upload.

The craft

For a rigger, the export step and the settings screen are the real licensing moment, not an afterthought. A creator wanting sole use sets personation permission to 'only the author'; one selling commissions is more likely to permit 'anyone' to perform as the avatar while withholding commercial usage, pointing buyers to a priced license through an additional-license field. A model meant for fan reuse can carry CC BY, while one for personal display can be marked redistribution-prohibited with no CC terms.

Keeping the creator in control

The per-model, per-permission structure gives finer control than one terms-of-service page, but only if the creator sets it, since guidelines only enforce whatever scope the author declared. Automatic stripping of contact metadata is a genuine safety feature, protecting identity even where a creator embedded contact details carelessly. This is an editorial observation, not a Hub statement: creators publishing avatars meant for a streaming persona should treat personation permission, not just the commercial toggle, as the setting tied to who can put the model on camera.

• Have personation, violent-expression, sexual-expression and commercial-use permissions each been set deliberately, rather than left at a default?
• Does the chosen Creative Commons option actually match what the creator wants to allow for redistribution and modification?
• Before reusing someone else's published model, has its specific license and any additional-license URL been checked with the author?

VRoid Hub's documentation treats a license as independent switches rather than one general permission, and a creator's actual control over their avatar depends on using all of them, not just uploading the file.
