Use UE4 as an external algorithm processing exe
Hi Guys, I am a Researcher/Scientist and I use unreal engine to prototype, develop and test some geometry processing algorithms. See one of my works here. What will happen is, we will be packaging it all into an exe and running it without GUI i.e. no rendering at all, but we will be continuously reading some numbers on say a UDP/serial port and publishing our final few numbers as the result on some other. Internally we are using Point Cloud Library as our work horse, so all the number crunching happens by it and another set of classes that I have developed. UE4 I am using as a convenient way for me to test that it all works with its rendering but in the final product package I don't use any rendering at all. I want to package this into separate non-visual exe and use it in combination with our company's propriety software that will consume the final published numbers. Now my question is will there be any royalties applicable on that ? I have tried to find a similar case here but I wanted to check with the Epic's legal experts if my case is different. Just need some clarity.

Your executable would be a "Product" under the UE4 EULA; but, because it will contain portions of UE4, it would not be an "Unrestricted Product". This means that, to the extent you monetize the executable, royalties would be due on revenues that do not fall into one of the royalty exceptions under Section 5 of the UE4 EULA. We encourage you to look at those exceptions, as there are many royalty free uses of UE4 under the UE4 EULA.
Additionally, please take a look at the Unreal Studio EULA, which may be more appropriate for your use. The Unreal Studio EULA is completely royalty free.
