yup, I decided that for the moment, I will focus more on detailing my ships - then when I make my next one I will try to incorporate nodes more - but details like spacescapes and the detailing neccasary to make a good ship, and obviously a good background.
I am currently looking at ways to maximize on the results of my planets, and a way to show how to model an asteroid (low polygon)... Hopefully these will all be in my next tutorial...
