At Geoguessr Go I was tasked with developing a 3D pipeline to build mobile optimized cities at a short time, that could be easily packaged into downloadable bundles, and outsourced with minimal instructions. To meet these goals we opted for a grid based tile system.
By making all surfaces single-color we could reduce the texture count to only one per city, using a simple color map texture. This way we could also reuse most 3D tiles for several cities by only switching out the color map.

All modeling and level building was made by me.
