There are two likely causes: • The plugin to read the necessary image file format can’t be found or wasn’t compiled. For the hang glider demo this is the .rgb file format (osgdb_rgb). You need to compile the rgb plugin in this case. • The program can’t find the data files it requires (textures). Make sure that you have downloaded the demo datafiles archive and extracted them. Make sure that the environment variables in the INSTALL file are set correctly, as these tell the viewer where to find the data. As of this writing they are OSGHOME, OSGDATA and OSG_FILE_PATH. To set the environment variables in Windows go to control panel->system->advanced->environment variables.
