Bridge Over Troubled Water

I doubt I can realize the project with quest3d. The main problem is the creation of a tile-based map, I've seen that unity has some plugins that can create it almost automatically, while using quest3d would be nearly impossible, or at least it would not be scalable.
I have to make more tests, but the advantage of using unity is that it has an enormous community plus a ton of plugins, it would be great if I could find one that lets you read shapefiles, this way I'd not have to rely on tiles but I'd directly read fully georeferenced tarrain data.
Quest3d also is a moribund program, I don't think it's worth to use it anymore.
