I had the pleasure to be the lead environment artist on Spacecraft at Shiro Games!
In early development I played a bit with Houdini to generate several asteroids to fill some parts of the space. The graphs can generate a wide variety of weird potato shapes and creates both a High poly and a uv-ed low poly ready to be baked! Everything is then textured with a smart material in Substance painter.
