This mod goes way beyond the title: The glass designs are great and all, but how you use the designs can make or break your experience! The glass can be partially embedded inside other nodes, meaning that you can make rounded/complex windows in many different ways. This may not seem like a lot, but it adds a lot of detail and beauty to any building!
The last example is my own design which has a window in 0 nodes! The trick is that the window node is hidden in one of the adjacent 'nodes' - this is with no changes to the mod, so you can do it too :)
