Just a word of warning. When you start playing more deeply with Motion, just don't get intimidated when you start realizing how extensive it is. Just go slow and steady. The fact that there are zillions of generators each with additional zillions of possible settings can kinda be intimidating to some.
Just use it to the level you need. And know that a career of exploring it likely won't let you try everything it's capable of doing.

I have used it extensively in earlier versions. In fact did a whole animation with it, but found that AE was much more what I needed. However since then I only use it for effects over like smoke etc.. But FCPX effects gives me an additional use for it. Its a great programme. Thanks for advice.
