EGIE So it’s kind of a process, because there’s no real UV mapping tools in sketchup. But, my process is this: I download the high quality tiles from Placemaker, then render out a single 8k texture from a top down parallel-projection view. Then import that new high-res texture map, align it with the topo surface (in this case it was super flat so I just used a rectangle making it easy) and reapply it to the surface. Then I just throw the same texture into the bump and reflection mapping slots and bobs yer uncle.
Sometimes I do some further tweaking in the texture, maybe some painting and clean up in PH. But it’s all pretty straight forward.
Now the road is pretty simple. That’s just geometry that I created and then projected down the map on top of.
I attached the color versions for reference
