Light positions using Corner Pin?

[Dan Ebberts]

Maybe you just need to stick your pickwhipped value into a variable and only use the x and y, like this:

temp = (your pickwhipped value goes here);
[temp[0],temp[1],value[2]]

Instead of value[2], you could also substitute any z value you want.

Hi Adam,

You will need to put this as an array,

Try this:

Drop down the position of the first light (hit ‘p’) Alt-click on the stopwatch to open expression editor. type ‘[‘ and then pickwhip the X value for the corner you want this light to be attached to, then type ‘,’ and pickwhip the Y value for the same point, then add another comma and then pickwhip to the lights own Z value (this will allow it to be adjusted)

The position expression of the light should then look something like this (with your layer/effect names):

[thisComp.layer(“Adjustment Layer 1”).effect(“Corner Pin”)(“Upper Left”)[0],thisComp.layer(“Adjustment Layer 1”).effect(“Corner Pin”)(“Upper Left”)[1],transform.position[2]]

Repeat this step for each light to each other the other points.

then set the Z value for each of the lights depending on how far forward in Z space you want them.

I hope this helps!

Tom

[thisComp.layer("Adjustment Layer 1").effect("Corner Pin")("Upper Left")[0],thisComp.layer("Adjustment Layer 1").effect("Corner Pin")("Upper Left")[1],transform.position[2]]
