Nothing much to write atm but i took a small break from this thing. Currently im working on that "logic" that draws the transparent faces (walls) and with some slopes that had problems previously, fortunately there is only 4 of them that need special handling when rendering them.

Im making them work face by face. Easier in that case. Not writing all out and then debugging.
Found more lighting examples, but i must review each of them, find their pros and cons and find one that works at the best in my case.
