Just a picture of some regular bushes in a neato new world. See the way the city turns upwards in the background? You can walk and drive around it naturally https://vrchat.com/home/world/wrld_c4e61164-c854-42d3-a70c-17d0d68a141b

Here's another world with the same concept, I prefer this one since it's a lot smaller and you can notice the gravity changing better https://vrchat.com/home/world/wrld_182dcca9-c877-4272-b8e8-8f265d419591
