Hi Robert, Glad to hear that things are working well for you!
The osgearth_seed application simply runs through a series of tile keys and tries to load them through the cache defined in the .earth file. If no cache is defined in the .earth file, then there really isn't anything for osgearth_seed to do, so it just exits early. I tried to add some support for normalzing the elevations of adjacent TerrainTiles in the TerrainTileEdgeNormalizerUpdateCallback class. It seems to work well, but can be kind of slow depending on how fast you zooming around. Are you seeing gaps between terrain tiles of the same LOD? We don't currently do any texel normalization of the images, but that would be a welcome addition to osgTerrain indeed. I'm curious as to how you were thinking of going about stitching together the adjacent tiles and if there would be a better way that through the update callback. Thanks!
