actually, tho shadowcats answer is mostly correct, there is an oversight in it that makes mapping uv's a real pain in the arse. when you use box mapping on an object such as indicated above, you have inside and outside normals. That is, the normals on the inside of the box point in..and those on the outside point out. notice that the normals of the box on the inside left, also point the same way as those on the outside right. Uv mapper draws the map based on the way the normals are on the model. this means that the exact same map will be applied to both of these areas, as will it be to the inside right/outside left, outside right/inside left, outside front/inside back, inside front/outside back...etc does that make sense? anyhow this will also be reflected in your coffin's texture. So if you want the inside of the coffin to have one texture, and the outside to have another, it requires more than just a simple "box" mapping. If you (or others) want/need more information on this just let me know and I'll explain further. :) BT
