3d follow - reflections and shadows
Posted: October 25th, 2007, 8:49 am
Help! I have to follow a new style format that was originally created for print but now they want video to "emulate" the same look and feel. Basically all objects are on a 3D plane and have reflections and shadows. My problem is that when I create animation for said object I have to create a reflection - I know how to create a static reflection in AE and so far what I do is flip the animated object invert it's y scale and move the position (by grabbing all of the keys) so that it is below the original. Without pre-composing (which would bork the 3D positional coordinates) how could I have the reflection follow the original? I have tried parenting but that doesn't quite do what I want. I have had some success with the following expression with having cast shadows follow the object:
temp = thisComp.layer("Juke Trio-spinning main 3").transform.position;
[temp[0], temp[1]+250, temp[2]-65]
but obviously this won't work for the reflection. I have my objects in a 3d scene with a back wall and a floor. Is there anyway to A - have an object follow the other but constrain it's Y position so that it never leaves the floor and B - Have a reflection actually mirror the main object without having to re-key certain sections?
I know - I want the world. What can I tell you - I hate having to key out something over and over and over....
