hello DAn

I dont suppose you mind revisiting this do you ??

I am trying to adapt the this to z value not scale ..

No luck so far but i will keep trying

this is my effort but it doesnt work (on the z position (i separated dimensions)

min= 0;
max= 1000;
L = thisComp.layer(“displacement image”);
sampleSize = 1;
point = L.fromWorld(toWorld(anchorPoint));
sample = L.sampleImage(point,[sampleSize,sampleSize]/2,true,time);
lightness = rgbToHsl(sample)[2];
s = linear(lightness,min,max);

It seems to work for me. In what way does it not work for you?
