Dan Ebberts Light Fall Off expression problem…
decay = .005; noFalloff = 200; L = thisComp.layer("Light 1"); d = length(L.transform.position,transform.position); if (d < noFalloff){ value; }else{ value/Math.exp((d - noFalloff)*decay); }I want to use Dan Ebberts Light Fall Off expression (https://www.motionscript.com/design-guide/falloff.html if you don’t know it) to add a bit more depth to a graphic sting I’m making, but when I try and use it, I get the message:
“After Effects warning: undefined is not an object.
Error occurred at line 6.
Expression disabled.”Any ideas?

Which version of AE?
Try changing line 6 to this:
d = length(L.position,position);

That worked perfectly, thank you!
I’m on 6.5, my boss is stingy…
Also, slightly embarrassed that you answered it! Your site has helped me so much, it’s very good :o)
