Hmm, I don't think the disguised brick thing is going to work. DTS objects seem to be rendered differently when it comes to lighting. Say you have a 1x4x5 brick. Using the 2 largest faces of the brick, say you have one that's well-lit, and one that's slightly shadowed. Then you put one of the false brick Doors right next to it. Compared to the well-lit side, it looks the same. If you look at the shadowed side, however, the Door is darker than the brick. So as it looks now, there would not be much point in making that Door if you can easily tell that it's the Door from a line of bricks. We tried, and it just didn't fit in.
