I am creating a warehouse enviornment using MAX and UDK. I was always told to preserve my poly count when creating enviornments for games and want to know what is the standard for creating things like bolts and screws, as my enviornment has alot of them.
Do I use decals? Do I just model the basic shape of the screw onto the model itself, then use normals to create the detail? Do I just use a bolt brush in photoshop, and create a normal from that? Do I use displacement maps? I have alot of these bolts all around and if I am going to be putting them all over the place on different objects and what not. Thanks!
