Not only selling the game, but ANY revenue produced with Unreal Engine triggers royalties, where the product is included. I'm posting the whole piece of the FAQ here, to remove all misunderstanding. 



**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](https://www.unrealengine.com/release) 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](https://www.unrealengine.com/release).



**What about downloadable content, in-app purchases, microtransactions, virtual currency redemption, and SUBSCRIPTION FEES, as well as in-app advertising and affiliate program revenue?**



> Revenue from these sources is included in the gross revenue calculation above.



**Why does Epic think its fair to ask for a percentage of a developers product revenue?**



> Our aim is to provide powerful tools, a scalable and productive workflow, advanced features, and millions of lines of C++ source code that enables developers to achieve more than they would otherwise be able to, so that this structure works to everyones benefit.



> In this business model, Epic succeeds only when developers succeed using UE4. Many of the industrys leading developers and publishers have signed up to license the Unreal Engine with royalty-based terms over the years, and now this level of access is open to everyone. And, don't forget, we continue to offer [custom terms](https://www.unrealengine.com/custom-licensing).



**Do I need to report royalties forever?**



> No, you only need to report royalties when you are making more than $3,000 per quarter from your product. If your game no longer is being sold, or no longer makes that amount of money, no royalty reports are due.



**What if my project requires custom licensing terms?**



> If you require terms that reduce or eliminate the 5% royalty in exchange for an upfront fee, or if you need custom legal terms or dedicated Epic support to help your team reduce risk or achieve specific goals, were here to help. See the [custom licensing](https://www.unrealengine.com/custom-licensing) page for details.



**What if my product is released through a publisher or distributor?**



> Youre free to release Unreal Engine products through a publisher or distributor, and the EULA gives you the right to sublicense the necessary parts of the Unreal Engine to them so they can release your game.

When negotiating terms with publishers, please keep in mind that the royalty remains 5% of the product's gross revenue after the first $3,000 per game per calendar quarter from users. In this scenario, feel free to refer your publisher to Epic during discussions, as it may be advantageous to all if the publisher obtains a [custom-negotiated](https://www.unrealengine.com/custom-licensing), multi-product Unreal Engine license covering your product.



**What if my project wins cash awards?**



> You do not have to pay royalties on award winnings.



**What if my product obtains crowdfunding via Kickstarter or another source?**



> Royalties are due on revenue from Kickstarter or other crowdfunding sources when the revenue is actually attributable to your product. For example, if the user is required to purchase a particular funding package to obtain access (now or later) to your product, or if that package gives the buyer benefits within the product such as in-game items or virtual currency.

Heres an example of what we mean by attributable: Assume you provide two tiers of offers, a signed poster for $20, and a signed poster plus game access for $50. No royalties are due on ancillary products like posters, so no royalty is due on the $20 tier. On the $50 tier, the user is paying for the poster with a $20 value, and that implies that the remaining $30 of value is attributable to the product. So, for each $50 tier sale, youd pay a royalty of $1.50 (5% of $30).





### Just based on that I suggest to remove CARLA simulator from the candidates list for Autoware.Auto in order to protect final users and OURSELVES of being trapped into unexpected royalties by Epic after sharing demo build with customer.



I agree there is no competition and we should include as many simulators as possible as far as it is not posessing a danger to Autoware.Auto end users.
