Royalty for VR simulations

Hi all

I have a question about the royaly free concept for architectural visualisation.
I want to make a VR exibiton for a Museum. If they want to sell this on DVD or something like that do they have to pay the royalty?

I know that simulatios an architectural visualisations are for free but i just wanna make sure.

Thx

Nobody will have to pay for the royalty as it is a simulation and not considered a game. You are also supplying it to them in a binary format and not source or engine format … so you should be okay.
