I tried Rigify and I found a very strange issue. After I painted full chest bone weight on body vertices, they are still affected by the neck bone somehow. I googled hard but it looks like nobody has a same problem like I have.

Would you like to help me to figure it out please?

  • $\begingroup$ Thank you for your help. I checked the article you introduced and it was very useful. Unfortunately, the weights on the list were all fine. Also, I'm terribly sorry that I accidentally uploaded different file. Now, the download link is fixed and I triple checked. Sorry again. $\endgroup$

    $\begingroup$ By displaying B-Bone it can be seen that DEF-spine.003 is deformed. $\endgroup$

  • $\begingroup$ Thank you so much! I thought something must influencing on it but I couldn't find it. Now, I need to figure out how to stop using b-bone but this is such a great clue to start from. Thank you again! $\endgroup$
