Yep. 0,0,-1667 based on default camera.

There may be a simpler way I’m not familiar with, but you just need to use a bit of math. If you had a 200 pixel square comp, and stuck the null in the dead center, it’s got a position of 100,100,0. 100px-wide squares would need to be arranged around that origin point—the “front” face would be at 100,100,-50, for instance, the back at 100,100,-100, one of the side faces would be rotated 90 degrees on the Y axis and placed at 100,100,-50, etc. Snapping and an easy way of adjusting anchor points for rotation such as the RepositionAnchorPoint script make it trivial to quickly do this; then you parent it to that null.
Note that you will sometimes get some fringes and gaps/seams in your cube, even if mathematically it’s perfect. Setting the cube faces’ blending mode to “Alpha Add” usually helps with that.

“Toggle Mask Shape and Visibility” is on, hence why I can see *some* of the null objects.

Well, you probably shouldn’t be doing H.264 renders directly out from After Effects; it tends to do a poor job, especially since it can’t do multipass (or at least it couldn’t in CS4.) Exporting out as a lossless file and then encoding in Media Encoder or your application of choice will result in a much nicer result.
-
Which version of After Effects are you using? I know in CC the H.264 option is gone because Adobe expects you to use the infernal Media Encoder.

To clarify: there *are* two keyframes; its initial position at A, and then moving to B. My question is if there’s a way to script it so that *only* keyframe B is affected by a parent expression.
Your idea about starting from the end is a good one for another project I’m boarding though! 🙂

That was just the ticket. Thanks for the link.

Ok I’ll try that now. Thanks.

Augh, that’s what I get for being careless. I meant to say 4444. This isn’t a render issue, it’s an After Effects behavior that’s stumping me.
This will hopefully make it clearer:
That top layer is set to screen. With nothing under it, it’s showing up (and exporting with the alpha) as black. That’s what I’m trying to address.

The exported file is ProRes 444. The issue is that within After Effects, a screened layer with nothing below it apparently defaults to showing it as black; outside the areas of the footage the transparency shows through in the comp window just fine. I’m wondering how to ameliorate this, if there is an option, from within After Effects.
