If every ornament is on its own layer, you can use the layer index to seed the random number.

freq = .5; //oscillations per second
amplitude = 20;
decay = 0; //no decay
seedRandom(index); // random seed based on layer index
offset = random(2*Math.PI); // offset amount for this layer
amplitude*Math.sin(freq*time*2*Math.PI+offset)/Math.exp(decay*time)

Did you change the name of the layer in the expression?

Give it at least 6 months before most of the new bugs are ironed out. I never update right after release of a new version.

If you split it at 5 seconds, you should get the desired result by changing the null layer name in the expression to be the same as the null layer that exists after that point (“Null 3” or whatever yours is called).

Does the new Photoshop have some function that the previous one didn’t that is useful to you? If not, just revert to earlier version.

Polar coordinates has an interpolation setting that goes from 0 to 100.

Sure, it’s pretty simple.

title is a variable
thisComp is the current composition
layer(“Rectangle”) retrieves the layer named “Rectangle” within that comp
sourceRectAtTime() returns the location and size of the layer (top, left, width, height) at a give time (usually the current time, but not always)
value is the current value of the property being accessed
title.width retrieves the width of the layer “Rectangle” (because that is what is assigned to the variable title)
[ ] (brackets) are used to create or access an array. Position is an array with 2 items, x and y.

So, long story short, we’re just adding the width of the layer “rectangle” to the current position.

The AE expression reference will give you more details.

Transform plus Echo, slight Tint for the blue if you want that look. Mostly a matter of tweaking the settings until it looks the way you want.
