Hi. I'm new to Gaea. Maybe my question is stupid and the answer is simple, but I couldn't find it. When I create a landscape with water features, such as lakes and rivers, then on the final elevation map, in these places, I get the height of the water surface. Is there anyway to get the height of the bottom of the reservoir in these places and not the surface of the water? I could just make a depression in place of lakes, but then I won't get the mask that I need to apply textures to the bottom of the reservoir.
