I found a great bit of research in the form of the tutorial below which is bound to help me in huge quantities, when i attempt to animate the leaf fly through in the scene. The tutorial is for 3DS max but will help me with the creative aspect of the process, rather than the technicalities of the program its running off.

After watching the tutorial i attempted a fly-through test for the project, i used the scene i was working on for the real project, however the test will not be the final version used in the actual project. I am extremely happy with the outcome of the test, however the fly-through the window needs to be a little different, and may need to be tweaked to increase the realism of the piece.
