Layer Control and Focus Distance
I’ve modified Dan Ebberts terrific Focus Distance expression so it can be keyframed, however it would be much easier if the Layer Control could be keyframed.
Is it possible to do so, either through a custom preset or another method?
Is this method the best way?
Here’s what I’m doing:
currentTarget = thisComp.layer("Focus Control").effect("Layer Target")("Slider");
currentTarget = Math.round(currentTarget);
target = thisComp.layer(currentTarget);
v1 = target.toWorld(target.anchorPoint) - toWorld([0,0,0]);
v2 = toWorldVec([0,0,1]);
dot(v1,v2) -

There’s no way to keyframe a layer control. I guess the other possibility would be to keyframe the layer names into a hidden text layer. It’s a little more trouble, but at least it shouldn’t get messed up (like a slider would) if you add new layers to the comp.

Dan, thanks for the reply. I’ve made a feature request to Adobe.
The slider method is a bit clumsy because its easy to mess up, I guess I’ll need to pay more attention 😉

You know, you could do it with (camera) layer marker comments, and that might even be more flexible that keyframes. It would look like this:
n = 0;
if (marker.numKeys > 0){
n = marker.nearestKey(time).index;
if (marker.key(n).time > time) n--;
}
if (n > 0){
try{
target = thisComp.layer(marker.key(n).comment);
v1 = target.toWorld(target.anchorPoint) - toWorld([0,0,0]);
v2 = toWorldVec([0,0,1]);
dot(v1,v2)
}catch(err){
value
}
}else{
value
}
The target would switch at each marker.
