There are some sites that sell 3D assets and textures, and generally other things that can be used in video games or 3D rendering. Some of these sites are Turbosquid, CGTrader, Sketchfab etc. I'm just wondering under what circumstances a video game developer who releases a title would be required to provide evidence of a license for a 3D game asset/model or anything else. In my mind it doesn't make much sense for anyone to have a right to demand the production of proof that a resource in a production (in whatever art form) is used correctly within a certain context. Wouldn't that be like me approaching Warner Bros and telling them that an ambient sound effect in the background of one of their films sounds suspiciously like one that I recorded, and that they need to provide proof of acquiring it legitimately or that its used under an appropriate license? Of course intuition personal intuition is often wrong, and it's likely that there is such a right.
In what circumstances does anybody have to demand or request proof?
The Sketchfab site license details page refer to an audit process that the licensee (the buyer of a model) is required to comply with:
"In addition, upon reasonable notice, Licensor or Sketchfab may, at their discretion, through their own employees or through a third party, audit Licensee's records directly related to this Agreement and use of Licensed Material or Licensee Work in order to verify compliance with the terms of this Agreement. If any such audit reveals any noncompliance with this Agreement, in addition to all other available remedies, Licensee shall reimburse Sketchfab or Licensor for the costs of conducting such audit."
I'm assuming someone like Sketchfab has the right to do this because it's included under the license agreement that you agree to before purchasing a model on their site?
