[1623] Physbone behaving weirdly
tracked
恨 Max
I have used this avatar for a very long time, and nothing was wrong with it until the "Drone Update" officially came out. I have tried multiple versions of the avatar as well. I have also asked friends who use the same avatar to test it, and it was always breaking. However, some people can see the bones misbehaving and some see it normally. Not sure what the issue here exactly is, but it seems like animated physbones tend to break now.

My issue with Phys bones unintentionally shaking is fixed with beta build 1744.
It was also related to another issue I figured out later that now got fixed.
Worth checking to see if your issue is also fixed.

[1626] PhysBone Erratic Behavior When Changing ParentConstraint Weight (Local Client Only)
＃かなたん
I've encountered an issue where PhysBone components exhibit erratic movement exclusively in my local client when animating VRC ParentConstraint Weight from 0→1. Other players in the same instance observe normal behavior.
Issue Details:
- I'm using ParentConstraint to temporarily change a hood's bone parent from Head to Chest during an equip/unequip animation
- When the animation transitions the Weight value from 0 to 1, the PhysBone components attached to the hood violently distort on my local client
- This behavior is completely invisible to other players in the same instance, who see the expected smooth transition
- The issue persists across multiple client builds, including the most recent update

My avatar still has PhysBone issues

It works correctly in Unity, but behaves unnaturally in VRChat.I have attached a video.

バージョン2025.2.1 アップデート後 PhysBoneバグ
た つ よ
しゃがみモーション（膝組）で衣装（コート）が震えるバグ発生
また衣装の裾が重力に逆らっているかのようにやや円形に広がるようになった
2025年4月30日まで以前のバージョンでは問題なく、5月1日の朝方にsteamからアップデート後問題発生
改悪アップデートの為、以前のバージョンに戻してほしい

I was advised by anatawa12-san that it might be a head chop issue, so I implemented it and it worked fine!
It seems that there was a lack of consideration when transferring from Head to another bone with ParentConstraint.
This was my lack of study...

[1622] Phys bones are unintentionally shaking / moving
Ronsterwars
The Phys Bones for my glasses and Flower are broken. The are shaking when I'm moving even though they shouldn't.
Here is a video from in game and the settings of the phys bone script.
