As someone who has done stuff and greatly enjoyed using Lightwave….the functionality I enjoy with 3D Invig. for appropriate projects (logo treatments and such)is the ability to see the interaction between the 3D elements and the effects environment (ie particle explosions where text hits the ground, the quality and nature of Shine eminating from the text). This allows me to alter 3d and/or AE interactively to get the desired intent. 3D Invig is not for all situations and does have limits…but what it does in conjunction with AE can be great stuff. Look at ayato.com to see some very nice work.
