Buzz, buzzzzzzz!
Instead of showing stuff that is pretty, here's a look at raw game development. This test bed is where I am setting up my procedural lod system, "nested procedural details." The trees procedurally generate the grass and the grass procedurally generates the bugs. Models are are ugly and poppy on purpose so that I can quickly iterate and know what is happening.
This tool is also how biomes work. The same grass species can spawn different insects depending on location and the same tress can similarly spawn mushrooms and birds depending on location.
