Prior to developing maps for a model you want to arrange the UV shells in a manner that will avoid certain game engine issues. In some game engines there is often an issue where the areas directly outside of UV shells bleed through into the game. This can cause a border to be very apparent around each UV shell and can ruin the overall effect. One method of avoiding this issue is through arrangement of the UV map. Though this process is a little extra time consuming, the little extra time spent arranging the UV map is very much worth it when compared with having to deal with a texture seam appearing as a result of not taking this step.

The general idea behind arranging a UV map is to place similarly colored areas of the model close in proximity to one another. This will allow you to apply a similar colored background behind these pieces so as to mask any seam that might appear. For instance, if the plan was make the hilt of a sword a dark grey color then all the UV shells related to that hilt could be placed in a similar location on the UV map. Then behind those shells a dark grey background could be placed. When the hilt is seen in game and for whatever reason the texture seams were to bleed through, the dark grey background would help to mask the issue. While the arrangement of the UV map is not always necessary depending on the model that is being developed, doing so is considered to be good form.
