Ok. I have just purchased the Virtual Forest Min Pack 4 but the following error sometimes occurs on imported 3ds and objs. I load one of the trees in to a blank scene... just to test it. If I render this in the MAIN Window, it renders fine but you can't save it... If I render in a new WINDOW, it becomes garbaged and crashes out.. I can't save the image to show you but.. it starts rendering and then bums out with vertical lines I took a capture to show you what I mean. Any ideas of a fix for this?
