Hi Aurora, I think what you are looking for is the osgTerrain::ValidDataOperator that you can attach to your elevation layer via Layer::setValidDataOperator(operator); In include/osgTerrain/ValidDataOperator you'll find the NoDataValue subclass which is probably what you want to use in your

Hi Chunk, The fuzziness you see is under sampling due to the texture being captured in objects space rather than in screen space - one texel on the overlay texture is being sampled by many screen pixels. Ideally you want a 1:1 mapping, but this is very hard to achieve and different algorithms
