I am trying to make caves in Unity. To do this, I am trying to use cellular automata. I found the following ([Rouge Basin Cellular Automata for Caves](http://www.roguebasin.com/index.php?title=Cellular_Automata_Method_for_Generating_Random_Cave-Like_Levels "Rouge Basin Caves")) that resembles what I am trying to accomplish.

However, the tutorial is not entirely what I want. I want something like what is produced by this website([Don Jon Caves](http://donjon.bin.sh/fantasy/dungeon/index.cgi "Don Jon Dungeon Generation")) with the "cavernous" setting (see image below).![enter image description here](https://i.stack.imgur.com/pGG8W.png)

As you can see in the image, everything is connected. I have tried numerous methods and libraries, however nothing has worked. 

I have been struggling with this issue for a while, and I would appreciate any guidance what so ever.

Thanks
