I think that sort-last rendering solve my problem. i understand that in sort-last the scene is decomposed across all machines in cluster. Then, there is a one computer which composes all decomposed parts into the final image and displays it on its own monitor. But how to implement sort-last in OpenSG? Any suggestions?
