Thanks for that Philippe, that has really helped me out a lot. I hadn't considered mixing both the animation toolbox filters and the orientation filters. I guess this takes up most of your time in a job? It took me a long time to get the effect I've been hunting for. Toward the end of your V5I showreel, there is a very complex scene with some vehicles flying between buildings, how on earth do you manage all the filters for something like that? There must be many keyframes and very complex filters there.
