The temple itself is supposed to be relatively new. However, I think a bit of damage here and there wouldn't hurt. But, as Freelancer said, making a somewhat new structure look damaged is a bit difficult. I will be adding damage, but it's going to be one of the last things that I do for this map. I started messing with it and came to the conclusion that it's going to be quite tedious, and that eats up a lot of time that I simply don't have.
As an alternative, I added a few lightbeams and saw that adding even one would make all the other openings in the roof look out of place. This means for every opening, I'd have to design some form of lightbeam. This isn't an option because of the sheer amount of custom 3dos I'd have to make that have to somewhat match each light path.
In turn, this brings me right back to where I started from--and that's only pissed me off even more since I don't have much time left to fiddle with the finer parts of this map. All I can do now is
