I'll try reading it from the json... Maybe just creating a 0.01 height block does the trick :D
Yes, it does export the model of the city, but it doesn't export the roads and fields... Or at least I am not able to find them importing the obj in Blender.
I love this tool. I'm using it for a Computer Vision project but I would need to export the roads and fields into the obj file. Is there a way to do it?
