[osg-users] osgEarth fading effect?

Hi, Similar to osgEarth which provides to set fading effect to the terrain tiles, could it be is possible to get the same effect directly from osg alone and how? Bcoz, to exploit that feature from osgEarth, it puts some constraints like the terrainDB should be generated with --terrain
