before you say anything, yes I do realize that tingalz is working on a space marine which is x1000 better and more accurate than mine, I realize ultramarines are really mainstream, I do realize im a terrible modeler with a terrible program, im doing this as a personal project to get better at modeling now that I figured out how to extrude things
you see that black thing there? whats causing it? will it do anything bad in-game? did I do something wrong?
