That helps alot, I thought the model I was using for terrain was to have polygon set to it only, now I get. I have one more issue but I do that other problem fixed. How do I set my model to land when it moving and I am jumping on a hill or slope? When I press the jump key and move on a flat surface he lands correctly but when I am moving and I press jump on a hill or slope he stay in the air until he gets to a flat surface. How do I change that?
