14 Checklist Items Before Publishing on UE Marketplace
Before publishing an asset on the Unreal Engine Marketplace (now part of the Epic Games ecosystem), creators should verify several technical, legal, and presentation requirements to avoid rejection and ensure a professional listing. Here are 14 important checklist items to review before submission:

FAQ (Frequently Asked Questions)
What happened to Unreal Engine Marketplace?
Many creators wonder what happened to the Unreal Engine Marketplace.
In recent updates, Epic Games began transitioning its asset ecosystem into a new unified platform called Fab.
The goal is to bring assets from Unreal Engine, Quixel, Sketchfab, and other sources into one larger marketplace for creators and developers.
Instead of disappearing, the Marketplace is evolving into a broader hub where artists can sell 3D assets, tools, and plugins to a wider audience.
For creators, this change means more visibility, improved discovery, and access to a larger global community of buyers across multiple creative industries.
How much does it cost to release a game with Unreal Engine?
Releasing a game with Unreal Engine can be surprisingly affordable for developers.
The engine itself is free to download and use, which allows indie creators and studios to build full games without paying upfront licensing fees ( ue marketplace ).
However, Epic Games charges a 5% royalty on gross revenue once your game earns more than $1 million USD.
Other potential costs may include asset purchases, marketing, development tools, and team expenses.
For many indie developers, this flexible pricing model makes Unreal Engine an attractive choice because you only pay royalties after your game becomes financially successful.
Can you make money on fab?
Yes, you can make money on Fab by selling your digital assets, tools, or creative content to a global audience.
Fab is designed as a unified marketplace for creators, offering opportunities for artists, developers, and designers to showcase high-quality 3D models, plugins, and game assets.
Success depends on presenting polished products, clear documentation, and appealing previews that attract buyers.
By understanding market demand, optimizing your listings, and consistently delivering professional-quality assets, you can turn your creativity into a sustainable income stream ( ue marketplace ).
Fab not only expands your reach but also connects you with a community of professionals looking for ready-to-use resources, making it a powerful platform for monetization.
What are the pros and cons of Unreal Engine?
Unreal Engine is a powerful tool for game development, but like any platform, it comes with pros and cons.
Pros: It offers stunning graphics, a robust physics engine, and a vast library of assets and plugins, making it ideal for AAA-quality games.
Its Blueprint visual scripting allows non-programmers to create complex gameplay, and it’s free to start, with royalties only after your revenue exceeds $1 million.
Cons: Unreal Engine has a steep learning curve for beginners and can be resource-intensive, requiring high-performance hardware ( ue marketplace ).
Smaller projects may face longer build times, and optimizing for lower-end devices can be challenging.
Can I get free assets on Unreal Marketplace?
Yes, you can get free assets on the Unreal Engine Marketplace ( ue marketplace ).
Epic Games regularly offers a wide range of high-quality free content, including 3D models, textures, sound effects, Blueprints, and complete project samples.
Some assets are permanently free, while others are available as part of monthly free giveaways, giving creators a chance to expand their projects without extra costs.
These assets are fully compatible with Unreal Engine and can save significant development time, whether you’re an indie developer or a hobbyist ( ue marketplace ).
Using free assets wisely allows you to prototype quickly, learn best practices, and enhance your games while keeping budgets low, making Unreal Engine even more accessible and inspiring for creators.
What are the risks of using a marketplace?
Using a marketplace can offer convenience and a wide reach, but it comes with risks that buyers and sellers should be aware of.
Key concerns include fraud, counterfeit products, and misleading listings, which can lead to financial loss or dissatisfaction.
Privacy and data security are also critical, as personal and payment information may be exposed.
Additionally, heavy competition and high fees can impact sellers’ profits, while inconsistent customer service may affect trust.
Being cautious, researching sellers, reading reviews, and understanding marketplace policies can minimize these risks and help users make safer, more informed decisions.
