I'm creating a terrain that will use the Temperate climate and will use a water map so that land types are calculated correctly. Mostly I want sand under water covered areas and grass above sea level. I need a full terrain texture that can be imported into the game engine as the texture for the terrain. Similar to the unique texturing in TGEA atlas. To do this I plan to export the texture map from L3DT as a png. The problem is that the texture map has all of the water covered areas shown in blue instead of sand. Is there any way to get the texture map to not show the water without disabling the water map completely? Without the water map the attribute map doesn't generate correctly.
I suppose another way to say this is that I want the attribute map but with the detail of the texture map.
