UE License - deployment to multiple servers


I am a student and I would like to know a bit more about the UE4 license. I know that the engine is free, and that there is a 5% royalty fee charged for each quarter making $3k+.

What I want to know is, say I develop a game and then want to deploy it to the cloud… do I need a license for each deployed instance, or pay a fee, or do I only have to pay that 5% royalty fee for the whole application, regardless of how many times it is installed, where it is installed, etc?

The royalty is collected per product/application/game basis. How your infrastructure is implemented (ie. deployed instances) to support what would be considered ‘the product’ is most likely left up to you. So, the boundary/granularity is at the product/application/game/SKU level. Consult your attorney.

Epic seems willing to work with people to be successful wrt to licensing:

As you’re a student, if this is a not for profit academic use, there is a license for that as well:

Whatever it is, if you’re making money with software margins, writing that 5% check every three months won’t seem so bad.

Best of luck with your project!

Thank you very much for your reply, @urMBN.
