Title: RE: Applying camera and layer matrices
Darrin,
Fantastic - this does it! You have my heartfelt gratitude and admiration! I certainly wouldn't have figured this one out on my own -- though my ego is at least gratified that this didn't turn out to be trivial. ;)

Brett,
I finally got some help with this and have an answer for you. The
short answer is that you want the transpose of the inverse of the
camera matrix for what you're doing. Here's an example plugin that
should do what you want:
In investigating this, we discovered a bug that means that -
cameraMatrixAtTime: doesn't work correctly with viewpoint cameras. I
have no ETA on when that will be fixed at this time.
Let me know if you have any other questions. And I apologize for the
length of time it took to get you an answer. We're pretty swamped at
work these days.
Darrin
