This procedural tool was developed to use any kind of mesh as an input. It runs on Houdini Engine inside Unity creating various styles of houses and cities while keeping low on polys (watch video for more info). The tool features LOD's, custom colliders, lightbaking, mesh inputs, speedtree inputs, procedural decals, low & high poly mode. If you're interested in the making of, I'm running a Polycount thread: https://polycount.com/discussion/203089/unity-shanty-town
