A very inspiring study about the logic that goes into creating a modular environment. As much as we don't like repetition, a race track has quite some repeating elements, might as well make'em look good. The study in particular is for 3dsmax/Unreal Engine, but the technique remains true regardless of the software used. You can READ IT THERE. And while at it, you might want to check the entire website, because it has some more similar topics. A few words about the author (full bio there): Thiago Klafke is an artist working for Blizzard Entertainment (at the date of this post ). But before that point, he started with modding, a bit like we all do here.
