Are you using display lists? Your first try should work to change the state, but you won't see the effects unless you dirty the display list; simply find all the Drawables under the node and call dirtyDisplayList(), which will recompile the display list with the new state. If you are changing state more than once-in-a-while, you may want to disable display lists instead (see Drawable::setUseDisplayList()); recompiling them all the time will slow things down (and is wasteful anyway). -- Bryan Thrall FlightSafety International [EMAIL PROTECTED] _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
