A new free add-on for Blender by Curtis Holt that can help you generate all kinds of designs.
The tool was designed to simplify the process of creating non-destructive, generative modeling styles in Blender 2.8. You can check it out in action below.
Basically, the tool helps users generate random designs which could be really useful for different sci-fi projects and alien designs. You could also try using it for tech and weapon designs.
