Elasticity and deformation in the Character Animator

[Eduardo Penner]

By placing the joints on the puppet's arm, it causes an elasticity that I am unable to resolve.
If anyone can help me, I will be immensely grateful.
Ps: i'm brazilian and the text was done in google translator, sorry if there is an english error.

I also used translation software.
I converted Japanese into English.

If you want the arms to be stretched
Add a behavior called "Limb IK".
A search on YouTube will show you how to use it.
Thank you.
