browser?

Hi all
I have just seen that some uses unreal engine for architechtual visualization.
I’m amazed how good this is…
I have one question. When making a scene where it is possible to navigate around and walk, What does someone need in order to view and walk in the scene…I mean if I share the scene with a friend to look…does he also need to have unreal installed or can he view a scene and navigate around in browser?

Sorry my bad english

If you package the project you are working on you can send it to other people without them needing the editor installed. All they have to do is open the .exe file.

Thank you very much
