I am looking to find out the legalities around UE4 and Visual Studio. For instance, I was looking to use UE4 at work for just demonstrating 3D construction models in VR to clients. I believe this means that royalty payment isn’t required (correct me if I am wrong) since it isn’t being sold. I also wondered what the deal is with visual studio. Is a license required for that software due to the size of the company I work in, even if only blueprints are used?
You’re right that the UE4 use you describe would be royalty-free.
As for VS licensing, that’s ultimately a Microsoft question. But I would encourage you to look into Visual Studio Community licensing.
An unlimited number of users within an organization can use Visual Studio Community for the following scenarios: in a classroom learning environment, for academic research, or for contributing to open source projects.
For all other usage scenarios:
In non-enterprise organizations, up to five users can use Visual Studio Community. In enterprise organizations (meaning those with >250 PCs or >$1 Million US Dollars in annual revenue), no use is permitted beyond the open source, academic research, and classroom learning environment scenarios described above.
