You'd generally want to blend straight into the opening CG though, so you'd be better off doing it direct in whatever 3D app you are making your animation in, or doing it in post using something like After Effects. My preference is for the former, as I feel it gives you more control. Sci-Fi 3D has a Max crawl setup available here
. It needs a little tweaking (or at least it did when I imported it into C4D to play around with), but it does the job.
