I have a comp with 410 layers that all have different positions. However, I need them to all have the same position expression:
seedRandom(0,true);
[transform.position[0],transform.position[1],transform.position[2]+random(0,thisComp.layer("General CTRL").effect("Slider Control")("Slider"))][transform.position[0],transform.position[1],transform.position[2]+random(0,thisComp.layer("General CTRL").effect("Slider Control")("Slider"))]
However, when I copy and paste the position track from one to the rest, it overwrites the position values as well as adds the expression. What is a way around this?
