Why editorialize? "Valve is not willing to publish games with AI generated content anymore" Your title changes the meaning- they didn't ban games afaict. It's also a misleading post, as it's specifically GenAI where authors can't prove or don't have rights to content. If you use ProcGen etc or have full rights to the data used, I can't imagine there would be any issues.
> we cannot ship your game while it contains these AI-generated assets, unless you can affirmatively confirm that you own the rights to all of the IP used in the data set that trained the AI to create the assets in your game. Yep, you are absolutely right.
i think valve is over reaching with this policy.
It should be that you need to prove the art used in the game itself that does not breach any copyright. The tool used to create said art has no bearing on the final art with regards to copyright.
Otherwise, would valve also have mentioned that the developer should also produce evidence of their photoshop license/subscription (if they used photoshop in the course of making their game)? Do they need to check that the version of windows being used to make the game is a licensed one?
