Hi Redbeard Do you mean a ripple starting from the middle and expanding outward? if so you might be able to do it with just one terrain and in the terrain editor,draw the ripples making them expand more in each frame , or maybe in an image editing program make a few differend geryscale maps of circles with different gradients to import into the terrain editor, and different points,and inverting them at other points,you might get more accurate circles that way. good luck and let us know how it works out.
