The avatar bundle validator only checks if the RigAttachment’s value is within its valid range. This range can be bypassed outside of the bounds by modifying the RigAttachment’s child, the “OriginalPosition” Vector3Value.
The uploaded avatar bundle will validate using the RigAttachment’s value but will be uploaded with the “OriginalPosition” value.
Thus the RigAttachment may be in range but the “OriginalPosition” will not be in range, and the uploaded avatar bundle will use the “OriginalPosition” values.
