I may be wrong but If you could find a group of birds flying in an image, take that group and make an alpha plane and save it in your objects for use when ever you need it. That way you want have to make a new group each time you need them. Position them different each time in your new scenes. You could do the same with poser birds when you get it. Save a bunch of different posed birds flying and then group them once in Vue to use again and again. :o) Poser and Vue work well together. I think you will like poser very well once you get it. :o)
