Fade as Move Away From Camera

Fade as Move Away From Camera

Just as you can reduce a layer’s saturation as it moves away
from the camera, you can reduce its Opacity. The expression
is, in fact, quite similar:
minDist = 900;
maxDist = 2000;
C = thisComp.activeCamera.toWorld([0,0,0]);
dist = length(toWorld(transform.anchorPoint), C);
ease(dist, minDist, maxDist, 100, 0)
The only differences between this expression and the previous
one are the fourth and fi fth parameters of the ease()
statement. In this case, as the distance increases from 900
to 2000 the opacity fades from 100% to 0%.
