Result of different configuration of network at each pass. In each image, you see the road network alone and the network with the control grid. I’m proud to mention that the generation time on a big network is taking around 500 millis, something easy to hide with a small transition.

Here, there are 3 + an initial road (the thick one). In each pass, the road becomes smaller and thinner.

It’s also possible to generate the same network with depth enabled. It’s becoming very complex to follow visually, but it makes no mistake 🙂
