Hey this looks awesome! Any updates on just a plugin vs the game. I am also trying to make a basic project where you create a real world height map png from Mapbox. There is a geojson file created to accompany this map tile png. The problem I am having is converting the geojson long/lat coordinates say for a road to unreal coordinates. I am trying to use the 4.27 Georeferencing system. This would in no way compete with your project. I am looking for some direction in how to convert the long/lat coordinates correctly so I can draw a road on the landscape from the imported heightmap. A more complete description of what I am trying to do is posted here if you get a chance to look at it How do you convert long/lat coordinates for a selected feature in mapbox tile geojson such as a road to Unreal Engine x,y coordinates? - Stack Overflow.
Thanks for your time and Cheers! Would love to know about your plugin, it really looks awesome.
