Mipmap control is located in osg::Image. You can tell if you want automatic generation or if you want to provide your own data for each level. In that latter case, you have to concatenate the levels in the data, and provide offsets to tell where in the data, each level starts. -Fred _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
