Since I never used the 3D MAX before, I used the Rhino program instead.
(Add base and adject the size of model)
(Build the construction of church)
(Make the building in the war, like broken several beams and timbers)
(Make the wall like destoryed)
And then make several small things, like broken cross, doors and windows.
Render without texture:
( Back)
(Right Front)
(Left Front)
(Detail in the model)
