but OMG it's sooooo hard to plan a city! specially if u need to have sliders going through the hole city..... the pink and blue cubes are just a mark, so I can make all the pinks taller and all the blues shorter, so I'm gonna get a checker pattern in the heights when the city's seen from far away.
The pattern was perfect before I adjust it to the rails I had, but it's impossible to make everythg fit perfectly when overlapped. So instead of keeping the pattern perfect I decided not to touch the rails. But I still think the effect's gonna work
