I made a post about this in the VRChat Discord server here, I'll just reencite my issue from there. https://discord.com/channels/189511567539306508/1405784687871398039 I'm having a very weird issue, this is 100% a bug. It has slight physics so it's definitely on the right object and not disabled, and it doesn't move correctly, The torso is kinda shaky and buggy, It's not world specific. https://i.imgur.com/30v6rqU.gif If the object has physics at all, it should have the overlay for it. It do9esn't even show on the overlay. I have taken some of the suggestions and done more testing. It is important to note that I have not updated the avatar for a few days, and there might of been a recent patch within the last couple days. It worked prior to this patch. It also works fine in editor. Here's a .gif screencap of that. https://i.imgur.com/taxa8BB.gif This uses Gesture Manager, without locomotion, and the physics here work fine. The Physbones and the anchor points go to an object that are seperate, so that shouldn't be the issue. I also set all the bones to be Simple to help jitter, but that wasn't an issue to begin with. I have also removed all the toggles with just the constraints and with the physbones, and even just the physbones. It works fine with just the physbones. My SDK is entirely up to date. Even the in-game overlay shows physbones entirely incorrectly, and to a degree, the physics are still getting applied to the bones as shown within the first .gif recording. I need this issue fixed pretty immediately because its inhibiting my work on something I plan to release as a product. Thank you! I can provide more information if needed. Edit: Done some testing with a few friends. It pinpoints to being a problem only locally with execution order of vrc constraints coming after physbones, when it should be physbones before constraints. When users clone my avatar, they have the issue, but from my side it looks fine, and I look fine to them. You can test this with two people using this avatar, and you'll see the local-global difference. https://vrchat.com/home/avatar/avtr_a74070b2-cad9-4ffd-9356-3630b0634d34
