Thank you Rutra, you were 100% correct with your 0% reccomendation. I had tried that but had done so at the same time as trying something else and everything came out badly. I now have 100's of thousands running poser people, streaming on without end, because I used a dynamic ecosystem. The render time is unspeakably slow do to the ecosystem calculations, but i'm setting up the render farm again and give it a shot on that.
