Hm…
I don’t have a lot of time right now but…did you checked “Comp Camera” in Invig’s Effect Window?
Another way to do it would be to make your 3D text, animate it, precomp/render it with an Alpha (only text, if you rendered it) then to import it in your comp, place it underneath your actual 3D text and play with the ramp/blur effects. Even the Smear effect from Pete’s Plug-Ins would probably work to do the blur (you’d probably have to keyframe the Smear position center point to your on the bottom of the “reflection” text).
Another way…would be duplicate your 3D text in Invig, put it under your upper (main) text, use a gradient as the layer map on your text…but you wouldn’t be able to add blur to it.
I’m sure there are plenty of other ways to do this but I just can’t think of them.
Good luck.
