You can read the commented lines in `tests/assets/list_nature_meshes.txt` for a partial list. There are also other types of procedural generators (lighting, colors, scatters, volumetrics, animations, etc) besides meshes/materials, which add diversity to the main rendering system but are not included in the commands below.
