Akilan, You are probably running out of texture units. In multitexture mode, osgEarth uses one per layer. Try using multipass mode instead:
MapEngineProperties props; props.layeringTechnique() = MapEngineProperties::LAYERING_MULTIPASS; MapNode* node = new MapNode( map, props ); Glenn Waldron : Pelican Mapping : +1.703.652.4791 On Thu, Apr 29, 2010 at 12:10 AM, Akilan Thangamani < [email protected]> wrote: > Hi Jason, > > In fact, I create the map through program.What the program does is that as > and when some new tif file arrives at particular folder which I am > monitoring continuously thru callback, I add the file to the already created > map.
