THNX SO MUCH

Mathematical shorter expressions:
(thisComp.layer("Null 1").transform.position[0]/thisComp.width)-0.5
(thisComp.layer("Null 1").transform.position[1]/thisComp.height)-0.5
(thisComp.layer("Null 1").transform.position[2]/thisComp.width)

Why we use expressions?
The problem is, that the NULL Object coordinate system ist pixel-based. The coordinate system of the particle system is relativ. So we must transform the values in pixel based.

TUTORIAL NOTES:

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

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

z=thisComp.layer("Null 1").transform.position[2]
z/thisComp.width
