Using UE4 for a Presentation at work

Can my company use UE4 to create interactive presentations for winning various construction projects?

For example, we would like to create a video with the ability to control it using programmed keys or remotes.
We can build this using UE4 but we would like to know if it’s royalty-free, given the fact that, ultimately, we are presenting this in order to win the project and gain profit?

Please note that we do not aim to sell the presentation material, but it’s worth mentioning that it will aid in achieving a monetised result.

Yes, that’s permitted under the EULA (royalty-free under the circumstances you describe).

I think a presentation with such a task, it should be the handiwork of real marketers, probably.
