So hi again.
Now i tryed the osgTerrain Nodekit. To gernerate my Terrain. i greated 2
TerrianTiles. But now the whole Terrian is very dark. Look at the code pls and
picture:
Sorry but the code tag dont work right.
osg::ref_ptr<osgTerrain::Locator> Locator1
= new osgTerrain::Locator;
Locator1->setCoordinateSystemType( osgTerrain::Locator::PROJECTED );
Locator1->setTransformAsExtents( 0.0, 0.0, 2560.0, 2560.0 );
osg::ref_ptr<osgTerrain::Locator> Locator2
= new osgTerrain::Locator;
Locator2->setCoordinateSystemType( osgTerrain::Locator::PROJECTED );
Locator2->setTransformAsExtents( 2560.0, 0.0, 2560.0+2560.0, 2560.0 );

osg::Image* img = osgDB::readImageFile( _Heightmap );
osg::ref_ptr<osg::HeightField> heightmap1 = new osg::HeightField;
heightmap1->allocate(256,256);
heightmap1->setXInterval(10.0f);
heightmap1->setYInterval(10.0f);
for(int z=0; z<256; z++)
{
for(int x=0; x<256; x++)
{
heightmap1->setHeight( x, z, (float)*img->data( x, z )
);
}
}
osg::ref_ptr<osgTerrain::HeightFieldLayer>
HeightFieldLayer1 = new osgTerrain::HeightFieldLayer( heightmap1.get() );
HeightFieldLayer1->setLocator( Locator1.get() );
osg::ref_ptr<osgTerrain::GeometryTechnique> GeometryTechnique1 = new
osgTerrain::GeometryTechnique;
osg::ref_ptr<osgTerrain::TerrainTile> TerrainTile1 = new
osgTerrain::TerrainTile;
TerrainTile1->setElevationLayer( HeightFieldLayer1.get() );
TerrainTile1->setTerrainTechnique( GeometryTechnique1.get() );

The red should be like the other pictures.
Thanks for help.
