Expression doesn’t work with keyframes
Hi, I’ve been searching the forum and I think I know where my problem comes from but I can’t get it to work.
I’ve made an expression with which I control the rotation of several layers of a precomp with a controller that is in another comp. The expression works great but when I apply keyframes it stops working. I’ve applied the expression to the rotation of the layer:
comp(“Binny_Front_FULL”).layer(“Brazo L”).transform.rotation
The precomposition has the time remapped with an expression to be able to select the frame that I want to show at any given time:
a=thisComp.layer(“Brazo Control L”).effect(“Slider Control”)(“Slider”)
framesToTime(a)
I think the problem comes from the remapper. I’ve tried to apply “valueAtTime()” in the rotation expression but I can’t get it to work.
This is the expression that I’ve applied without success. The rotation works until keyframes are applied to animate:
C = comp(“Binny_Front_FULL”);
ctrl = C.layer(“Brazo L”).transform.rotation;
L = C.layer(thisComp.name);
ctrl.valueAtTime(time+L.startTime)
I would appreciate help on this.
Thanks a lot!

L = C.layer(thisComp.name);<div>
</div><div>I’m assuming you do in fact have a Layer labelled “Binny_Front_FULL” in your Comp. If not, that would cause non-function. </div> -
Haven’t had time to test it out but try this instead:
C = comp(“Binny_Front_FULL”);
ctrl = C.layer(“Brazo L”).transform.rotation;
L = C.layer(thisComp.name);
remappedTime = L.timeRemap.value;
ctrl.valueAtTime(remappedTime);

Hi, thanks for your reply.
I have te remapped layer and the controller inside <b style=”font-family: inherit; font-size: inherit; color: var(–bb-body-text-color);”>“Binny_Front_FULL”. The remapped layer hav an expresion and inside it I have the layers I want to control.
<b style=”font-family: inherit; font-size: inherit; color: var(–bb-body-text-color);”>Everything works fine til I create a keyframe in the controller

Hi Yoan, thanks for your reply.
Your expresion doesn’t fix the problem. Works fiine until I create a keyframe.
Thanks!

Hey Fernando, does this help?
C = comp(“Binny_Front_FULL”);
ctrl = C.layer(“Brazo L”).transform.rotation;
L = C.layer(thisComp.name);
remappedTime = L.timeRemap.value;
ctrl.valueAtTime(remappedTime + L.startTime);

Hi Yoan, the same as befoe.
I have restarted the configuration and the expressions to avoid to use time remapping and works fine.
Thanks for your time!
