New photogrammetry data for Japan on the left. Previous autogen & OSM building data on the right by BlackShark.Ai.
Might want to consider a tiny bit of colour correction on rooftops and building materials to escape that green-tinge we see globally so objects visually blend together better. Not just a matter of photogrammetry having day-lit baked lighting data in the textures but also partially that existing building materials are a touch bit drab.
