Hi Zuzana, One way to have different rendering in different cameras is use a seperate osg::Camera::setCullMask(uint) on each of the Cameras and then a matching NodeMask above different subgraphs that you want rendered for each of the cameras. The osgstereimage provides an example of this in action, abeit for stereo.
