not quite a tutorial, but i have a timelapse of the whole thing:
Short Version, 8 minutes more for people who want to see it go from zero to done: https://www.youtube.com/watch?v=Du-ryvJWHaA&list=PLHPl0SFKkUjMeEMD6ezJlo5-gocTunlCX

Long Version: full view of blender, 2 1/2 hours long: https://www.youtube.com/watch?v=xTwOaSSMqAk&list=PLHPl0SFKkUjMeEMD6ezJlo5-gocTunlCX

The key thing I did was to atlas every tiling texture, then cutting up the mesh into evenly sized quads to apply the tiling manually, though to get effective culling it is wise to plan your layout around it, which is what the houses do as they block a lot of view and therefore avatars.

There are a few more tricks so I may do a commentary kinda thing soon, but i kinda want to take a bit of a breather for now.
