[Papervision3D] Rotation and coordinates

[hernan torrisi]

This is an After Effects - Papervision problem.
I am making a papervision project and the space coordinates work differently than the after effects ones. My camera and objects should behave similarly in AE and Papervision.
I wrote a script to export all the camera and layer positions and rotations as an XML to import to flash.
I got half way of solving this but i am stuck.

- In AE I created a null object to attach all the 3D layers so their coordinates are (0,0,0) at start.
- I inverted the Y position on each layer with an expression, so positive values go up and not down.
-The rotation is the problem. I can´t understand the logic of rotating the objects so they behave similarly in both cases. I tried with both orientation and rotation from after effects but i think they are the same.

If anyone can help i´d really appreciate it.
thanks!
