Linking a layer to part of a Puppet Mesh

[Guest]

Hello,

So basically I have two seperate animated layers and one of them [ The secondary ] is supposed to be attached to the other [ The main ] but for ease of animation I seperated them. Now, I want the secondary layer to be attached to a part of the main layer's Puppet Mesh without adding a Pin to the mesh because adding a pin will sacrifice the movement factor of that specific part of the mesh unless I animated it which will just cause more hassle.

I used the expression below and it worked but the secondary layer isn't following the main's movement which results in an unaturally still animation.

l = thisComp.layer("PUPPET_LAYER");
l.toComp(l.effect("Puppet").arap.mesh("Mesh 1").deform("Puppet Pin 1").position);

Is there a way to attach the secondary layer to a part of the main's mesh so that the secondary follows the movement of that part specifically?

Long and short: No. Unless there is a pin, there is nothing to link to. The mesh data itself is not in any way accessible. You have to change your setup or manually move stuff around.

Is there a way to add a pin or maybe a null to the specific area that doesn't effect the mesh? I thought of motion tracking the layer and having a null to the area but the motion tracker option is grayed out whenever I try to do it.
