The size of the stage is set to (0.0f,0.0f,1.0f,1.0f). Is that what you meant? Or do i have to set it to something like (-OSG::Inf,-OSG::Inf ,OSG::Inf ,OSG::Inf )? > Beyond that I'm not sure where to look for the problem, it sounds a bit as if > somewhere the modified near value is cached and not updated correctly, but > why does it update the first time you change it?
