Hi Alex, The OSG by default has small feature culling enabled, but this should only effect very small objects. Could this be the case?
You can set what type of culling you want in our application by the changing the CullingMode via the osg::CullSettings object. osg::Camera inherits from CullSettings so the usual way to control the culling mode is: viewer.getCamera()->setCullingMode(osg::CullSettings::VIEW_FRUSTUM_SIDES_CULLING); Robert.
