Sorry, I’ve been asleep at the switch. :)
Try this:
L = comp("Main Comp").layer(thisComp.name);
C = comp("Main Comp").layer("Camera 1");
p1a = toWorld(anchorPoint);
p1b = toWorld(anchorPoint + [0,0,1]);
p2a = L.toWorld(p1a);
p2b = L.toWorld(p1b);
v1 = p2b - p2a;
v2 = C.toWorld([0,0,0]) - p2a;
if (dot(v1,v2) < 0) value else 0

precomp Hi
But thanks again for giving it a try.
The expression i want is also way over my head, hence me asking the group
here ;-)

oh right. I guess you'll need to find an alternative to the toCompVec function then. Something you use with a null instead of the comp camera. Unfortunately that's way out of my territory. |
