Expression for duplicating Layer, each positioned further in Z space

I suggest you watch this tutorial by Aharon Rabinowitz (again )
I liked it very much
maybe you don’t need to figure out an expression after all…

anyway

z =(index -1) * 100;
[value [0], value [1], z]

I gotta check out that Z scale thing again, I forgot all about it.

But with expressions, here goes. Add this expression to the position of a 3D layer (it effects the Z spread) and you get a 100 pixel spread from the top layer.

position+[0,0,(index-1)*100]

If you add a Null layer (put on bottom of stack) with a Slider Control and pickwhip the last “100” in the expression to the slider you make it real easy to change the spread between you layers in Z Space, change the slider and they all change evenly (right click the slider number to change the range if you want more than the 0-100 default).

Here’s the expression with the Null and Slider:

position+[0,0,(index-1)*thisComp.layer(“Null 1”).effect(“Slider Control”)(“Slider”)]

is it possible to do this but have a different frame on each layer? eg same movie clip just advanced in 1’s 2’s or 3’s that way i would only have to rotoscope the movie and not have to convert to tga and do each frame (yes i did that before!!!)

Thanks for th tips guys!
I’ve got another one for ya:
in addition to placing layers back in Z space, I’d also like to have them shift first to the right, then back to the left, then back to the right in a smooth s-like shape or pattern.
Example (in 2-d)
L
L
L
L
L
L
L
L
L
L
L
Etc.

It would be a huge bonus to be able to control the distance of each layers relative placement, perhaps the depth of the curve. What do you think?
Any takers?
Cheers,
Marc
