Hi Doug,
It sounds like 3D Invigorator PRO for After Effects is the right product for you. It easily lets you import 3D models directly into AE and also gives you the same modeling capabilities that ProModeler does. As far as modeling is concerned, you are able to draw any object in 2D and have it extruded and beveled in 3D space. This means you won’t be able to make dancing dinosaurs, but you will be able to make any logo and text in 3D space. It’s also very common for users to find 3D models from other websites then import them into 3D Invigorator PRO.
With all of this said, 3D Invigorator PRO is great for importing models, but it uses AE’s keyframes to animate the objects. Since you are new to AE I’m expecting you might not be a whiz at keyframes yet. If this is the case then I suggest looking at 3D ProAnimator. ProAnimator has everything that 3D Invigorator PRO does plus an entire animation engine. It makes it super easy to animate hundreds of objects at the same time.
Hope this helps,
Alex Dow
