This looks amazing! I have a question/feature request though: Do you have plans to support OSM files? Alternatively, if I convert an OSM file to a JSON file using ogr2ogr, will the City Viewer support it?
There's a mod for Cities Skyline that exports an OSM file of a city, and I wanted to see if I can't convert the OSM file to a JSON file and then have your City Viewer generate me a 3D model that I can then take into Tabletop Simulator or FoundryVTT via the 3D Canvas.
I am sorry but the answer to all these questions is no. Currently I am not planning to support any osm formats because I have zero knowledge about osm and converting osm xml to json won't help because json the City Viewer requires is generated only by the applications of the Procgen Arcana family. Maybe one day someone will make a converter from osm to this custom json format...
By why do you even need the City Viewer? This is just a minor tool to support the city generator and other generators of mine. Aren't there better applications capable of exporting 3d models?
