Layer opacity based on proximity to a camera.
I’m trying to automate an effect, where as a layer gets within 100 pixels of a camera it begins to fade out and at say 10 pixels it disappears. It will probably fade back up when the layer passes the camera but that’s okay.
The idea is that when a camera is pushed through 3d layers they will autmatically fade out.
Any help will sure save me some time… Thanks,

A bit of a kludge but this works bases on Z position, won’t work otherwise. Attach to Opacity of layer.
T = 100;
camZ = thisComp.layer(“Camera 1”).transform.position[2];
myZ = transform.position[2];
diff = 100 -(camZ+myZ);
if (diff > ( 20)) {
T = diff ;
}else{
if (diff < 0); T = 0; } T -
This should do it:
dist = length(position,thisComp.layer(“Camera 1”).position);
linear(dist,10,100,0,100)Dan

Very Cool! Thanks for your help guys.
Brian, very Ambitious, but as you probably guessed I need to have it work from every axis, although I think I have learned how to arrange an “if” scenario.
Dan your script is like candy. I’ve printed it up and am going to enjoy it tonight after dinner. Beautiful.Thanks again buys,
Andrew
