Hi, I have a terrain scene load from a terrain.osg file, I can see data like hightField and imageLayer in the terrain.osg file.
So, when I use osgDB::readNodeFile to load the terrain, osg will auto generate the TerrainTile -> Tile -> Geode -> Geometry scene graph for me base on those data, right? Problem is, after I changed the geode's stateset of a tile, like, give the geode a new textureUnit. Save the root node of terrain to a newTerrain.osg will not contain data relate to the changes. newTerrain.osg only have data as the old terrain.osg file, but nothing related to textureUnit change. I know I can save the geode node to a geode.osg file which contain info of textureUnit change. But how to merge the geode.osg file to the newTerrain.osg file, so when I load the newTerrain.osg, it will auto load the corresponding geode.osg and add it to the right position in the scene graph? ... Thank you!
