Our program loads terrains fine and clips models appropriately when they go "under" the terrain. Our program also allows the user to add an "overlay" terrain on top of the base terrain. The problem we have now is that the elevation data of the overlay terrain is lower than the elevation of the base terrain. This causes the model to disappear at certain camera angles because the base terrain is clipping the model out of the scene.
I've tried various methods to no avail. Is there any way to "cut a hole" in the base terrain the size of the overlay terrain? Thanks, Blake Blake Williams DRS TC3 Inc
