In that case, you still place everything in a big union. Make 2 copies of your 
source with altered names. One for the colour part, one for the z information.
Make your animation twice, using exactly the same parameters.
OR
Using switching variable:
Do the first part, say colour, MOVE to another folder or RENAME the resulting 
images.
Change the switch and repeat the animation.
The goal is to get 2 sets of images, one set full color, the other for depth 
information.

You need some external toot for that.
