i tried to put tree's in gulch but everytime i try to do it. it doesn't appere in the swap list. I used the map rebuild guide and still that didn't work. what must i do to make it work ?

ow damm just saw that i made a mistake
I ment put a skin of a tree

well if its just the skin go to bitmaps in the map that has teh tree u want then click save, then u can go to bg and go to the object u want to have the tree skin on and hit import and import that skin in there.
