how can i make a building cloak itself, but nothing else no matter how close? i need this for a explosive trap, kinda like the demo trap on generals...
depending on the size of the building (bigger buildings work best), you could make it a stealth generator, with range of 1. for a small building, try a range of 0.1 and see what happens.
look at tiberium sun if you are not sure how to make a cloaking generator, or look around, someone will have documented it.
