Can purchased commercial 3D assets for graphic renderings be sold on Adobe Stock?

I have no intention of selling original photos under a CC0 license.

But why does Adobe Stock accept so much CC0 content, like NASA photos and other well-known images?

There's a lot of this kind of content, and they somehow accept it. Why aren't they still blocking these authors? Is it because the photos are modified and a new derivative work?

A CGI artist who creates, for example, landscape renders with purchased 3D nature assets under a commercial or CC0 license also has a legal derivative work a render with copyright. So there's no risk here, as long as you have copyright and legal licenses to create rendered graphics.

I recommend carefully reading the entire Adobe Stock terms and conditions.

"By submitting content to Adobe Stock, you agree that you own or have a license to the copyright in the content."

I have legal "licenses" and proof of purchase for the graphic renders I've created using 3D assets under a commercial, royalty-free license. Therefore, these renders can be sold to Adobe Stock and other stock agencies, provided it's a custom composition of the graphic render scene and the 3D assets aren't on a plain background. 3D assets based on a well-known object protected by intellectual property are also avoided.

On the Adobe Stock Discord, moderators write that selling renders is permitted provided a commercial license for the purchased 3D assets is legally purchased.

Adobe Stock has millions of renders, and I doubt any CGI artist would create renders from scratch in a graphics program without additional 3D assets. Provided they have legally purchased commercial licenses for these 3D assets.

Explain this. Why does Adobe Stock accept CC0 licensed images if the terms and conditions don't allow it?

Type Nasa or famous paintings into the search engine.

Understanding copyright

You must own or control all the rights to the files you submit to Adobe Stock. Don’t submit files that don’t belong to you, such as photos taken by your spouse. Don’t incorporate anything into your content that was created by someone else — not even images you got from a website that allows free downloads — unless you have a complete property release from the owner of the other content.

By way of example, you may not upload content that is lifted from third party sites (such as Unsplash or Pixabay). You may also not submit content that is too similar to the expression of another individual or entity’s work.  

Don’t submit what you believe to be public-domain content 

Don’t submit content created by other artists, including content available as a free download at any location 

Don’t submit content that’s partially based on the work of other artist

Hope that helps.

In addition to commercial licenses, I also ask the authors of 3D assets if I can sell landscape renders to stock agencies. They answer yes. A representative from Superhivemarket also agreed. So it has legal validity.

The terms and conditions on their website do not explicitly prohibit commercial sales through stock agencies.

I would not! You probably do not have the exclusive ownership.

Thanks for the replies. However, it's best to buy 3D assets from reputable sellers who have a high sales volume, social media presence, etc., and with a royalty-free commercial license without any restrictions on rendering to stock agencies. Avoid unknown asset sellers, especially those who don't have their own companies. This is probably the best approach.

So basically you are buying a car, and you are asking other drivers if you can legally own the car if the car is stolen? 

My guess is: even if Superhivemarket allows the use of the assets to create renderd asset of their models, I would not use them to create stock assets, except if I would have substantially modified the 3D build. And please do not ask me how substantially you need to modify the asset. 

Have you read the Stock Contributor Agreement?

Specifically clause 4, IP rights. Can you be certain that you have legally obtained the rights to the assets upon which your renders are based? And would you be able to prove that you have such rights? I don't know whether such assets are considered to be in the public domain, but if so, Adobe does not allow such assets to be submitted to Adobe Stock.
