It would indeed be extremely useful if you could force random() to produce the same random sequence in different layers and properties. I think seedRandom needs a third parameter – global = true, but alas, as you discovered, it doesn’t exist.

Try this:

L = this_comp.layer(“Layer 1”);
s = L.scale/100;
u = L.to_world_vec([s[0],0,0]);
v = L.to_world_vec([0,s[1],0]);
w = L.to_world_vec([0,0,s[2]]);
sinb = clamp(w[0],-1,1);
b = Math.asin(sinb/this_comp.pixel_aspect);
cosb = Math.cos(b);
if (Math.abs(cosb) > .0005){
c = -Math.atan2(v[0],u[0]);
a = -Math.atan2(w[1],w[2]);
}else{
a = Math.atan2(u[1],v[1]);
c = 0;
}
[radians_to_degrees(a),radians_to_degrees(b),radians_to_degrees(c)]

Substitute your layer for “Layer 1”.

If you’re talking about the stacking order of the layers, you can select the bottom one, shift+select the top one, Edit>Cut, Edit>Paste.

I’m not sure exactly what you’re asking, but wouldn’t you want to do it the other way around? For example, you could put a null at the same position as your footage and make it the parent of the camera, then you would rotate the null to move the camera in a circle. You could time-remap the footage and use an expression to pick which frame to show based on the rotation of the null. Then auto-orient the footage towards the camera.

Or am I completely on the wrong track?

I’m guessing that you’re animating the shape of the mask, correct? If so, tracking should work, or a script could apply the position of the end vertex at each frame to your bud layer’s position. A bit of work, but certainly educational. 🙂

Which expression are you using. If you want each layer maintain its initial relationship to the null, you can modify the last line like this:

start = 0; //start time of template motion
end = 4.0; //end time of template motion

t = thisComp.layer(“template”);
offset = (t.effect(“offset”)(“Slider”)/100)*(index -1);
travel = linear(t.effect(“travel”)(“Slider”)/100,start,end);
value + t.position.valueAtTime(travel – offset) – t.position.valueAtTime(0)

I think that should do it.
