I would suggest modeling the fairway of the course in a different program...including the green. This will settle all issues of scale and so on. Once you have this, you are ready to add the hills and adding textures, and lastly, the animation that you are looking for. Try modeling the fairway in Bryce as a plane, or in a separate program (my favorite vice is Form-Z), and import it as a 3DS model. You will have control over pitch, angle, and everything else, not to mention better environmental renderings. Hope this was some help.
