nearestKey from other layer
Hello.
I usually use:
d = Math.abs(time – nearestKey(time).time);
easeOut(d, 0, .1, 100, 0)Which retrieves somthing like 3 keyframes with just one. This works fine working in a layer.
I want to use a layer reference (A), to this layer will be linked 2 solids 1 and 2.
Solid 1 will take value information form the keyframes, as usual (Just picking with pickwhip)
Solid 2 Just take the position of keyframe to change it’s opacity like a camera flash.I’ve tried many and many expressions, but I can’t solve.
Thanksd = Math.abs(time - nearestKey(time).time);
easeOut(d, 0, .1, 100, 0) -

You didn’t mention which Layer A property you wanted to respond to, so this assumes Opacity (just change the first line if that’s not correct):
// solid 2’s opacity expression might look like this
prop = thisComp.layer(“Layer A”).transform.opacity;
d = Math.abs(time – prop.nearestKey(time).time);
easeOut(d, 0, .1, 100, 0)Dan

Hello Dan.
You are a genius, and you are right, sorry, Layer A is a control layer, and the property to change is a checkbox.
Expression works perfectly, I just modified the first line and voilá, I think I didn’t defined well the first variable and of course my expression didn’t works.
Best regards
Jano.
