Puppet Tool/Auto trace not capturing the full image

[kp65128755]

I'm using the puppet tool and the autotrace is not capturing the full illustration and therefore when I move the puppet pin, it's cutting off the image. See image 1 vs. 2. Is there a way to manually increase the scope of the region traced via auto trace? I tried using "expansion", but then it started to distort the animation.

I'm using After Effects CC 2018 THANKS in advance!

Increase the mesh density in the tool options.

Had the same issue, you should increase expansion:
