Controlling Layers inside a Precomp
Hi.
I’m new to expressions. I’d like to learn to control elements within a pre-comp. Is that possible.
For example:i ma working in a composition called Maincomp.
Layer1 is a null. It has an Angle Control in its effects.
Comp2 is a pre-comp which contains the layer Square inside of it.
Can i use the angle control in Layer1 to control the scale of Square?
many many thanks!

Sure – the syntax will look something like this:
temp = comp(“Maincomp”).layer(“Layer1”).effect(“Angle Control”)(“Angle”);

Ok, but going a bit further…
on the main comp, i got a camera, that is already rotaded and etc…
inside the pre-comp there is a 3D layer… how to make it always “looking” into the camera angle? -
Something like this:
c = comp(“Maincomp”);
l = c.layer(thisComp.name);
p = l.fromWorld(c.activeCamera.toWorld([0,0,0]));
lookAt(p,position)Dan
