What kinds of products can I release with Unreal Engine 4?
You can release any product that is allowed by law, with the exception of gambling applications and certain safety-critical control systems described in the EULA. You can release games, demos, VR projects, architectural showcases, trailers, films, and more.
The only parts of the Unreal Engine you can’t release to the general public are the source code and tools or modifications to them; these components may only be distributed to other licensees with access to the same version of the Unreal Engine.
What do I need to do when releasing a product?
You must notify Epic when you begin collecting revenue or ship your product; see here for more details.
If I release a commercial product, what royalties are due to Epic, and when?
Generally, you are obligated to pay to Epic 5% of all gross revenue after the first $3,000 per game or application per calendar quarter, regardless of what company collects the revenue. For example, if your product earns $10 from sales on the App Store, the royalty due is $0.50 (5% of $10), even though you would receive roughly $7 from Apple after they deduct their distribution fee of roughly $3 (30% of $10).
Royalty payments are due 45 days after the close of each calendar quarter. Along with the payment, you must send a royalty report on a per-product basis. For more information, see here.
