Using GSAP distribute to project backward z transform

[Asderex]

Hi,  I am trying to use the GSAP distrubute utility function to add negative z axis transforms to a bunch of elements (i.e. project away from the viewer).  I have used the following tween:

 

gsap.to(".staggerBackward", {
                z: gsap.utils.distribute({
                    base: 0.0,
                    amount: -500,
                    from: "end"
                })
            })

This results in GSAP applying positive z axis transforms to all .staggerBackward elements (i.e. toward the viewer).  I tried changing the amount to a positive but this results in more positive transforms but this time in the opposite direction.  Any ideas what I'm getting wrong / not understanding about this one? Thanks in advance

Facepalm ........ The correct answer was to use {base: -500, amount: 500}.... of course I thought of this after posting the question.
