Hello all. I am not a steady user of After Effects but I have something i am working on that I think would be best done in this program. If I want to take a couple of objects from 3dsmax and then rotate them all and have the objects transition to one another, can it be readily done in AE? An example would be a baseball, a round bowl of same diamter, and maybe an apple. All 3 would be rotating but only 1 would show at a time. I was thinking that using layer with transitons would work but what do I know...

You'd still have to align everything in your 3D program first, but of course you can do all sorts of fancy transitions in AE, including this over-stylized sphere thing that was prevalent in many TV ads last year.
Thank you Mylenium. I did some searching and it seems the shape transition thing is done a good bit in 2D motion graphics. I can't imaging it is much different in 3D objects but I get burnt every time I say or think something like that. 🙂 It makes sense all of the rotating objects need to be imported at same origin. As for the transition, it would seem you could animate in a certain time the turning off of one object and turning on the other. Again, this is me just nievely thinking this out.
Shape transitions work by animated mask paths from one keyframe to another. Because your shapes sound like they will all be the same shape (ball, bowl etc...) it sounds like it might be simpler for you to look at effects like:
CC Glass Wipe
CC Image Wipe
Reshape
The first two effects distort one image to reveal another, but the reshape filter allows you to morph images from one mask to another.

The best way to approach this is to simply render a full 360 turntable for all objects with a sufficient duration so you have enough frames to work with. Then you can easily trim and retime everything. Of course there could be any number of additional effects like 3D layers in AE sweeping in sync with the rotation, particles swirling around and all that. Really depends what you have in mind. It may be useful to create a storyboard to pin down your ideas since this apparently lives by execution and timing rather then complex technical setups.
