when double sided - the polycounter counts them as 2 polys (faces), I presume since it has to render each side of the plane.
So I have 2 straight planes (long walls = 4 polys), the two end walls with that follow the roof rise -(8 polys) and a double sided debris, i believe.
So it should be down to 13 once the debris is taken care of, and If I change the end walls to a straight plane. then the total count will go down to 9 (8 on all walls, 1 on debris). 9 faces on a dead shape at LOD0 -
Largest BMP is 256x256 for the debris - rest are 256x128, roof is a tilled 64x64
