Are you saving '.ive' files with inlined textures by any chance? Once a texture is applied/used its associated image data by default is removed from memory to save space. This means that the image *data* cannot be saved to disk anymore (but the file name can). You can prevent this by calling 'setUnRefImageDataAfterApply(false)' on the textures. _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
