HI Mo, If you want to use the result in a separate window/display you'll need to copy the result back to an osg::Image and then use this image on another texture on the other windows. osg::Camera supports attaching an osg::Image to it and will automatically copy the frame buffer(or FBO) to the image, and osg::Texture* all are able to detect an update to an osg::Image so will automatically download the result, so it's possible to do this wiring up relatively easily, but.. performance won't be great as it requires a round trip to the CPU/main memory.
