Was sick yesterday so no Vue or internet. better today. I will work on a short tutorial on this function later on. But for Tim just a short tip. My waves were too big initially too. I'll save them for a storm. But the qick and dirty way is to just flatten the terrane. Go to one of the side views and find the middle handle on top of the terrane and pull it down toward the ground. It also helps to set the original ground plane to the same water material. so any "holes" wont be noticable Don't forget the clip slider either. Then its just play till you get the right 'for you' settings. The atmospheres will give much different appearances to the same water also. I like a water with some foam in it so don't neglect the material editor either. Approach this as Play -glenn
