Shameless plug coming up… but I’m currently developing CityGen3D which is a Unity asset that automatically creates a 3D environment based on a real world location.
You are able to generate Unity scenes from any position in the world, as it downloads the map data for you based on the location you specify.
So for example, if you were creating a driving game and wanted levels in London, New York and Singapore, you could use CityGen3D to create each of these scenes for your game.
Not sure if it’s exactly what you are looking for, but thought I’d mention it in case it was of interest as I’m hoping to have a beta available in a few months.
Here’s a rendering of Gibraltar to give you an idea of the type of thing it can do.
I have more closeup screenshots on twitter @CityGen3D .
I also have a thread on the Work In Progress forum if you are interested in following development: [RELEASED] CityGen3D | Procedural city generation from map data
Either way, good luck with your project!
