I am rendering to disc which i think helps and it's really just an ecosystem (well ecopaint on billboard preview) I was doing a fairly easy scene with trees in the eco but still got a warning. I haven't been using vue for that long, probably a month so maybe there are settings I am not quite sure of at the moment which will help.

BB just found the thread, it was monkeycloud http://www.renderosity.com/mod/forumpro/showthread.php?message_id=3965105&ebot_calc_page#message_3965105

I might try rendering a lower res one and  play around using it on lights.
