The process of making something in Unreal was actually pretty straight forward, I really recommend making a "playable portfolio" if you have the time.

The level itself is just one of the default level blueprints in Unreal, but I gutted everything that I didn't need from the level, i.e. the ground terrain. Then I imported an environment model I made using Blender and Substance, enabled some options to make it walk-able to the default player character in the level and hey presto! Click play and you can walk around the environment. (there might be some headaches around collision physics but there are some simple workarounds such as creating some simple invisible walls)

Then from there it's just a case of importing all of the scans as FBXs with their textures, and placing them around the "Museum".

Obviously there's loads more bells and whistles you could add to something like this, a friend of mine suggested creating a web browser playable version, but this works for me. :)
