I created a Billboard with Rydia on it, Ok it rendered right in B.A.T. and looked right in Lot editor... and the icon for the item is right in SC4 but when i place it in my city it is just a greenish blue blurry area bigger than the actual item, never seen this and i have made many billboards but never this problem.. what is wrong with this B.A.T.?
Can you please provide a pic. It's hard for us to guess from your description.
