Glad you got it working! Is there a reason you didn't just attach an osg::Texture to your camera and set the number of samples greater than 1 in the attach call? By the way, if you change OpenGL state, be careful that you restore the previous state or tell OpenSceneGraph about the changes you make (via haveAppliedMode(), haveAppliedAttribute(), etc.); otherwise OpenSceneGraph will get confused about what the current OpenGL state is. -- Bryan Thrall FlightSafety International bryan.thr...@flightsafety.com _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
