After clicking “Publish,” Roblox Studio shows this error: “Content does not pass validation rules: RightUpperArm is skinned to a non-standard joint HumanoidRootPart. Body parts may only be skinned to standard R15 joints.”
None of the avatar’s joints are skinned to the root part — they’re all skinned to standard R15 joints.
Has anyone encountered this issue and found a fix? Thank you.
Thank you for reporting this issue. We have assigned to our team for further review.
Hey there. This message is coming from a recently added validation test that checks that the skinning weights from body parts do not refer to virtual joints (e.g. joints from the head). If you are willing to privately share a body model that is failing, we’ll take a look at it.
Yes, sure, I’d appreciate your assistance here. I’ve DMed you.
Hi @TopcatRB , thanks for your report.
You are unintentionally hitting our new skinning validation due to improper joint naming (Part instead of Node). You can check the expected joint names here.
Please try renaming this joint in the FBX file and see if you still get this error.
Thank you! This resolved the issue.
