Parenting puppet tool
Hi, I’m doing a piece of character animation and i need to parent an eyebrow to a pin from the puppet tool. I’ve seen some code on the web but can’t seem to get it to work. If anyone can explain how to do this simply I would be extremely grateful.
PS. I’ve tried to parent the position of the eye brow simply by dragging the expression pick whip to the pins position but it seems the co-ordinates are drawn from the layer and not the whole world.

Something like this:
L = thisComp.layer(“face”);
L.toWorld(L.effect(“Puppet”).arap.mesh(“Mesh 1”).deform(“Puppet Pin 1”).position)Dan

Thats amazing Dan, works great. Could you help me with one more thing? Is there a way to move the pin without effecting the mesh as if you were pulling it out and repositioning it elsewhere?

Not that I know of, but I’m no expert on how Puppet Pins work.

Just ran across this thread and wondered if anyone knew an expression to achieve the opposition. . . parenting a puppet pin to a null? Thanks.

Like this:
N = thisComp.layer(“Null 1”);
fromWorld(N.toWorld(N.anchorPoint));Dan

I know this sounds minorly random, but I’m looking for this same sort of parenting technique, since I’m animating multiple compositions with balloons in them. Where do you enter that coding at? I did a quick google search on it, and I didn’t find much.
Thanks!

It depends on what you’re trying to do exactly.

Well I have never seen the coding part of after effects, at all. I didn’t realize there was a section where you could add coding (such as this for the parent tool for the puppets.) How do I access the general coding section?

The kind of code we were discussing in this thread are expressions, which you enter by alt/opt+clicking the stopwatch for the property that you want to control. A text-entry area opens in the timeline, and you enter (or paste in) the expression there. An expression can control/animate the property to which it is applied, but nothing else.
The two other types of coding for AE are scripting and plug-ins. Scripts can be developed in a text editor or the ExtendScript Toolkit. Plug-ins would be developed in the IDE appropriate to your platform.

Wow! Thank you for that! That will come in handy!
