Hi Carl, Please download http://www.openscenegraph.org/projects/osg/attachment/wiki/Support/Tutorials/NPS_Tutorials_src.rarand test Tutorial_06 which is given link osgHud in OSG website by you. I have already tried and it is working pretty good. I think your problem was that you didn't control model's path. So you can't see any hud on the screen. Please control all path's on your system and recompile it. You will see all of them works.
