When using the Puppet Warp tool, can you keyframe the mesh expansion value?

[Neon Tundra]

Hi there! How's everyone? I have an illustrated character whose beard is animated with the Puppet Warp tool. The transition to the next scene is a big zoom in, and there's a problem: the 'expansion' value I had set for the mesh disortion doesn't scale along with the character. I see this artifact that breaks the image, which happens when the mesh is too small for the object, but I can't add keyframes to expand this 'expansion' value of the mesh. I thought I could parent this value to an adjustment layer with a slider control and expand it from there, but it doesn't let me either. All I could do was fade out the opacity of the effect before the illustration zooms in, but that's just a workaround, not a proper solution.

I hope I'm making myself clear. Thanks in advance to anyone who knows how to solve this!

Cheers,

Luigi

AFAIK, larger meshes only affect rendering time and should not affect anything else. Let us know is this is not the case.

You're on the right track - increasing the Expansion value will prevent artwork from tearing.  However, you're also - as you've noticed - hitting a dead end. 

You'll want to create, or recreate, the Puppet Tool animation at its largest size such that the zoom results by the scale change ending at 100%.  Let's say your current animation goes from 100% scale to 400% scale, then you want to recreate it such that it goes from 25% to 100% instead.  While this should work fine with a corresponding layers parented to a Null Layer for the scale change, it's probably better to do it via a nested Composition and make sure the Collapse Transforamtions remains off in the containing Comp.

Hey there Warren, how are you? Sorry for my late reply. Thanks for the advice, I'll keep that in mind next time, very useful!

Have a wonderful day,
