The edge of my track ballast looks unrealistic because the edge is so straight and it even looks like the whole track bed is raised off the grass. I've tried to replace the ballast with a different aclean file from the download files that is suppose to have an uneven edge but it doesnt seem to help. The edge is still very straight. I have seen great screen shots and the track ballast looks lose and like it blends into the grass so well. Any ideas on how to change this?
