Hi Anyone, I need to fix this ASAP. I am using OSG 2.4+ with old Producer Config files. OSG creates slave cameras for my multiple window configuration (one for each). The resulting settings are not quite like specified in my configuration file. Field of Views are mostly OK, but it is altering the

I tried adjusting the point size using osg::Point but it still had no effect. By the way these points are actually osg::PointSprites if that makes any difference. I queried OpenGL using glGetFloatv to find out the range of supported point sizes on the machine and it returned 0.0 to 64. I
