"When a collection of Japanese homes using submeshes to create a "yard" were released on the workshop a year or two ago, I was immediately interested in applying the concept to my own creations. Since I've been 3d modeling homes recently, I decided to revisit Cities:Skylines and the concept.

The image shows a personal proof of concept. The yard mesh is actually the main mesh (the fence shader wouldn't work with it otherwise, for whatever reason). The house, fence (terrain-conforming), and garage are all submeshes.
