I just noticed when it posted my comment for moderation that it says I entered (\"Null 1\") when I actually pasted ("Null") right from the expression?

Hi

I am trying to complete your tutorial on 3d Stroke Effect. I am using the current cloud version of Adobe After Effects for 2014 on my Windows OS. I am trying to enter the expression for the x position on the particle effect. This is what I entered:

x=thisComp.layer("Null 1").transform.position[0]-thisComp.width/2;
x/thisComp.width

However as soon as I try to pickwhip it to my Null 1 object it immediately changes the expression to:

thisComp.layer("Null 1").transform.position[0]

and it doesn't work. I have ensure the Null Object is set to a 3D layer.

If you had any suggestions or could point me in some direction I would greatly appreciate it!

Kind Regards,
Heather

Hey, can't get the equation for particle world z position to work right. The other two work fine. Is there another equation or another way to link particle world to a null object?

Whereas I realize this question is a month old, I just solved the same problem. You may have forgotten to turn the null object to 3D before writing the expressions.
