Excellent! Thank you so much.
I set the auto-orient to “face camera” and set the center as the layers parents – and now I can control that perfectly.
I also changed the code so that it only made 18 items (the max I am going to have) in the array:
X=Math.sin(degreesToRadians(360/(18)*index))*radius;
Y=100;
Z=Math.cos(degreesToRadians(360/(18)*index))*radius;
Many Thanks, James.
