Hi,

But I'm ok with slizing things up into 64x64 hunks. > > I am not familiar with this class. > osgTerrain has a ContourLayer class, which takes a 1 dimensional transferfunction (osg::TransferFunction1D), the osgTerrain has a section of code where that ContourLayer is assigned to the ColorLayer of the terraintile. I assumed that the intention was to use color bands for depicting the altitude (contour) of the terrain, but maybe I'm mistaken Thank you!
