Hi people How would i go about creating a mountain/hillside terrain that would have a hole in it. Similar to a cave opening. I have tried creating a terrain (making that positive) and then making a big rock (making that intersect) and then group both together. That did not work. Thanks in advance for any help.

Hi Sking In the terrain editor,you need to make your terrains solid rather than hollow( as they are by default) select "Make solid"from the drop menu under the grid resolution selector. The boolean operation should work after that. Be sure to do it for both terrains. Hope this helps Hawkfyr
