This may have something to do with the way TerrainTile normally uses a Locator object to position it and scale it into the real 3D world. This is something done for you by VirtualPlanetBuilder/osgDEM. I've never done it by hand. > I also noticed that when I use osg::Terrain::TerrainTile/HeightFieldLayer > the loading time increases significantly (for 2000 by 2000 I get 70 > seconds). This could also be a result of some misconfiguration. Try building the tile database with VPB/osgDEM.

I think you can modify the HeightField and then just dirty() it. > Cheers, > Janna -- Chris 'Xenon' Hanson, omo sanza lettere Xenon AlphaPixel.com PixelSense Landsat processing now available! http://www.alphapixel.com/demos/ "There is no Truth.
