Selling what you make: what each store allows
A plain guide to the AI rules at the Unity Asset Store, Fab, itch.io, Gumroad, Superhive, TurboSquid and Envato, as of November 2026, and what Ava prepares for each.
Ava can download a folder prepared for a store: the layout, formats and checks that store asks for. That never means the store will accept it. Only the store decides. What follows is what each one asked for when we last checked.
First: this is AI-assisted work
When Ava writes the steps that Blender or GIMP carry out, treat the result as AI-assisted, even when you directed every step. No store we checked has said otherwise, so declare it. Declaring is yours to do: Ava never declares anything for you, and How-this-was-made.txt in your download gives you the facts to do it with.
If it is true of your work, wording like "Made with AI assistance, directed by me at every step" is a starting point. Change it to fit the store’s rules and what you actually did.
Stores that take AI-assisted work
Unity Asset Store
Unity requires anything made with the aid of AI, completely or in part, to be disclosed in the listing’s “AI description” field: in plain terms, naming the specific AI tools used, and describing every change you made that adds value. A few more Unity rules catch people out. Words that suggest work done by hand, such as “hand-painted” or “drawn”, are not allowed on AI-assisted work. A description written purely by AI can be rejected. The icon, card and cover images must be rendered in the Unity Editor, so a render from Blender cannot be one of them. Fonts or textures under licences that require attribution (such as CC-BY, Apache 2.0 or GPL) are not accepted. New publishers can submit 5 packages a month, rising to 20 after six months. Ava prepares one root folder with .fbx models and .png textures. The .blend files are zipped as source, and a Third-Party Notices file lists the fonts used with their licences. A checklist covers what is left to do in Unity, and Ava checks texture sizes, the pack’s size and path lengths.
Fab
Fab requires every product to be tagged “CreatedWithAI” when a material part of it was made with generative AI, and its definition includes AI that aids the creation of new content. So treat a model Ava built as AI-made there. Fab’s own licence covers your buyers, so a licence file of your own in the download does not apply, and Fab refuses material under GPL-style licences. Ava prepares one zip per format (FBX, GLB, Blend), checks each model’s scale against a 1.92 m human, makes a 1920 × 1080 gallery image, and writes a checklist. Fab does not take loose image files as a product: its 2D categories expect Unreal Engine, UEFN or Unity projects. Ava’s 2D zip can only go along as an extra file on a 3D listing, so it comes with a warning.
itch.io
itch.io requires every asset page to answer the AI Disclosure section on the project’s edit page, and it enforces this strictly for asset packs, even when the AI output was edited afterwards. Pages that should be tagged and are not are dropped from browse and search. itch.io also asks you to say so in the description, and treats mass-produced AI pages as spam. Buyers get itch.io’s own licence as well as yours. Ava prepares your folders as they are, with a License.txt for you to fill in.
Gumroad
Gumroad has no AI rule of its own. You must own or hold the rights to what you sell, you cannot resell what you did not create, and you must not misrepresent a product’s authorship or licence, so saying how it was made is the safe course as well as the honest one. Ava prepares your folders as a zip, with a License.txt for you to fill in.
Superhive (Blender Market)
Superhive does not take products that are fully AI-generated with little human input. It allows tools where a person makes the creative decisions, and AI-assisted models where you have put in serious documented work, and it may ask for evidence. It strongly recommends saying how AI was used. Its minimum requirements include logical English names for every part, and Blender’s default names (Cube.001, Material.004) are not accepted. Ava packs each .blend with its textures inside and checks the names. How-this-was-made.txt is the evidence of who decided what.
Stores that don’t
- TurboSquid does not permit models developed using AI tools, and its publishing agreement makes sellers promise their work is not the product of AI. Work made with Ava cannot be sold there.
- Envato (GraphicRiver, 3DOcean, Elements) does not allow AI-generated content as an item or as the main part of one, and is not taking open author sign-ups: new authors join by invitation or selective intake.
Ava still lists both, marked as not available, so you know why rather than finding out after you have uploaded.
For your own game
Godot is not a store: its Asset Store has no paid assets yet. If you are making your own game, Ava can download just the .glb models and finished images, ready to drop into a Godot project.
What is always yours
- Your listing. Ava can help you word it, but she won’t write the whole thing for you. Some stores require it to be your own.
- Your licence. Ava gives you a blank License.txt where a store needs one, never a choice of licence.
- Licences for fonts and anything you brought in. Ava shows the licence she knows of, but check it at the source.
- Whether your work is protected by copyright. That depends on where you live and how it was made, and work made mainly by AI may not be protected.
