I have a comp with 100's a 3d layers staggered about through 3d space. The camera trucks backwards through them. I am trying to mimic a LOD methodology, and have the layers opacity drive of it's distance from the camera.
I am able to drive the opacity off the position of the camera, (thisComp.layer("Camera 1").position[0]/10) but I can't figure out how to access the measurement of distance from each layer to the camera.
Any thoughts? Thanks in advance for your help.
Layer Opacity based on Distance from camera

This will get you started
var maxDist=1000
var p1=thisComp.layer("Camera 1").position;
var p2=position;
var d=(length(p1,p2)/maxDist)
100-(100*d)
Cheers,
Dave
