Hi Robert, I have already looked at the example(s) on osgText (both comes with source code and in tutorials on the net), but could not find anything. The weird thing is it is a quite easy task, but I have no result. I use OpenSceneGraphversion 3.1.2 and Visual Studio 2010 on Windows XP. Is there any bug report or a tricky part should I know?
