UV islands are the chunks of UV's. So for example, don't unwrap a box and weld the sides together, keep them 6 separate pieces. The reason you want every face a separate smoothing group is because the edge where they connect is really sharp. For example, a cylinder can be 2 smoothing groups. You can assign the faces that…
It depends on what program you use. For example in Maya you can (in the Polygon Menu) go to Normals->Soften Edge while having the edge selected. In 3dsMax, you can use smoothing groups
Alright, so this is kind of a stupid question, but I was wondering what the best way to make a hard edge look not-as-hard would be? For example, say I have a single brick, a 6 sided rectangle. How would I make the edges look softer once it's all textured and whatnot? Would that be through the normal map? If so, how?…
