Hi Vince,
While Invigorator does many things very, very well, its ability to deal with objects imported from other 3D aps is somewhat limited. For example, it does not support all of the texture mapping options you’ll find in Cinema, Lightwave, Maya, etc. Nor does Invigorator import IK, object parenting or deformations. For those reasons, I wouldn’t consider Invigorator a bridge between Cinema and After Effects. Invig does offer basic object import functions but in many cases, your better option would be to render movies from Cinema and composite them in After Effects.
Having said that, Invigorator does offer huge advantages over Cinema and the other aps I’ve mentioned, when it comes to creating certain kinds of animation very quickly and easily. I would much rather build flying logo and text animations in Invigorator Pro for After Effects or in ProAnimator, than I would in any other 3D application out there. No other apps can touch the speed, power and workflow advantages. In some cases, Invigorator’s ability to export models for use in other apps is also useful.
Hope this helps.
Jon
