How to do a correct shoulder deformation? So, I’m rigging a character in Blender and I’m having a bit of trouble with the shoulder deformation. Namely the region under the arm as seen here:



I was trying to replicate this I saw here:

Shoulder deformations

But the instructions aren’t very clear and I can’t seem to download the file from BlendSwap as the site just keeps giving me an error every time I try to login.

So, I was hoping someone here with some rigging experience could help me out with this. I’m just scratching my head here at this point.

Blend:
If what's bothering you is what's happening on the armpit, switch to Weight Paint mode, select a Blend > Subtract brush, Strength 1, activate the 2D Falloff option in order to paint through, and paint.
