point object forward, not toward camera?
I have some text floating at the end of some 3D lines. Picture a rolled up porcupine, and words floating at the end of each needle. I want the words to point toward the camera direction, but not look at the camera. If they look at the camera then they angle themselves.
The camera doesn’t actually move around, so in this case I realized it Might be easiest to just link the position only, but not the rotation. But my lines all intersect at the center of the screen, and I need positions for the end points of the lines.
So my thought was to parent a null object to my line, then use an expression to attach the text position to the Null position.
Well, if you’re more experienced than me, you’re probably aware that didn’t work. I need an expression that would take the world coordinates of the null. But I’m striking out in finding that.
I also tried to use the first position and add it to it’s parent. The initial position was correct, but I think it is always staying in a positive direction or something. I’m not exactly sure what the math is doing, but it’s not what I was hoping for.
Am I headed the right direction in that I need world coordinates? Or is there a more efficient route to take?

Shoot. After a coffee my google skills suddenly started working.
Dan Ebberts to the rescue. He posted up the answer somewhere else. I used this, and it’s like magic.L = thisComp.layer(“Null 3”);
L.toWorld(L.anchorPoint);
