I own Invigorator Pro and use it in AE for some things. It’s a great plug-in for AE. It’s really easy to bring in a client’s vector logo and extrude it, bevel, at Shine to it, and poof, you have a nice logo treatment for the opening of a piece. And being able to bring in a 3D object and rotate the thing or do 3D beveled text is great too.
If it could be applied to Motion layers, that would be great.
But being able to bring in a 3D object or extrude a logo in Motion and not have to go out to a 3D application is something a lot of people would want to do, IMHO.
