I have a question about the camper. Does it end up having a ton of faces and creating lag in game if you use a few of them? It looks great though!
No. In fact, I'm pretty sure it has fewer polys than many vehicles in blockland today. If you think that I keep the faces from the bricks that are not visible, I don't. Also, I combine all faces that can be combined and make sure I have the minimum number of polys for the model to work.
