I can't say that I have. That'll be something I should tinker with. In retrospect, and with in-game conversations, it's come to my attention that when it comes to in-game use, smooth shading would likely make it more detail intense than necessary. As far as real rifles go, it's not uncommon to see high end rifles with a more boxy look. If I proceed to make a match grade or display rifles where detail is more appreciated, this is where I would have to be more observant of the texture. For the purposes of this particular rifle, the flat shade is more practical. Since I will be getting more into the smoother textures as time progresses, I'm still interested to learn what I can.
