In my quest Red Dawn, I am having you walk under a part of rock. I want to make it sure that you walk under it when your on the bottom part, but so you walk on it on the top part. And also I made a bridge to cross a gap, but you can walk under it, but I cant walk on it, only over it. I made it layer6. Help is appreciated.
