Wow...When the preview of G3D came out, I changing the level and graphics and everything (you can edit the .x files with notepad). It wasn't TO hard if you knew what you where doing but i couldn't actually make something that looked good...I could only make it so the head had a random stick coming out of it or have 2 heads or have feet for hands ^_^
And no...the graphics every very simple unless you wanna worry about lining it up with the 3D cords correctly
