Hi Brian, State leakage in the OSG normally suggests that your osg::Geometry don't have tex coordinates, normals or colour arrays assigned to them so they are just inheriting them from what was last sent to OpenGL, if you add more models then the draw order will jump around and your ill conditioned models will inherit a far wider range of state, exactly what they'll inherit will change from frame to frame.
To fix it you have to find out what models are poorly conditioned and are missing required arrays - if a particular model has a problem then convert this one to .osg and have a browse through it to see what arrays are present and which ones are missing.
