Exaclty, that's the point. I think what diego needs is something different from what the StreamingRenderer is supposed to do. This is why I am asking details about what he needs to do. If he has some specific needs I can drop some ideas that would help him to get very high perfomances even with enormous coverage. You have seen a few time the experimental viewers I have for coverage with enabled pyramids, they are really fast even if the coveerage are big.
