[ENG] Continuing the NebulaRig breakdown series,
I’d like to show the next module — Limb (arms/legs).

The core idea behind this module was simple:
the limb should always be able to switch cleanly between IK and FK.

Key features:

— Seamless IK / FK switch
Guaranteed switching at any moment without changing the pose

— IK Stretch
Controlled limb stretching

— Soft IK
Anti-pop implemented through segment length adjustment,
without shifting the IK handle
→ stable behavior and safe switching to FK

— Pole Vector Follow / Snap
Additional control over elbow / knee behavior
(including the ability to “lock” the joint in place)

— Bendy + No Corner
Smooth deformation without sharp angles in the joint

— Offset Controls (Translate / Scale)
Additional layer of control over shape and segment length
(Scale on X acts as segment length)

— Save Volume
Volume preservation based on current segment length

Like the rest of the system, the logic is built using Bifrost,
keeping the scene clean and the system scalable.

[RU] В продолжение серии постов о NebulaRig хочу показать следующий модуль — Limb (руки/ноги).

Основная идея при разработке была простой:
конечность должна всегда корректно переключаться между IK и FK.

-

Ключевые возможности:

— Seamless IK / FK switch
Гарантированное переключение в любой момент времени без изменения позы

— IK Stretch
Контролируемое растяжение конечности

— Soft IK
Anti-pop реализован через изменение длины сегментов
без смещения IK handle
→ стабильное поведение и безопасное переключение в FK

— Pole Vector Follow / Snap
Дополнительный контроль поведения локтя / колена
(включая возможность “упереться” в точку)

— Bendy + No Corner
Плавная деформация без острых углов в суставе

— Offset Controls (Translate / Scale)
Дополнительный уровень контроля формы и длины сегментов
(Scale по X работает как длина сегмента)

— Save Volume
Сохранение объема в зависимости от текущей длины сегмента

-

Как и остальные модули, вся логика реализована через Bifrost,
что позволяет держать сцену чистой, а систему — масштабируемой.

[ENG] For over a year, I have been developing NebulaRig, a modular Bifrost-based auto-rig system.

The main goal of the project is to create a highly performant and flexible rig capable of scaling across different production needs — from film to real-time pipelines.

The system is built on a Bifrost computational architecture, providing procedural logic, stable evaluation, and clean module separation.

NebulaRig consists of independent modules connected through a Guide Point (GP) system.
This approach allows modules to be connected, reorganized, and expanded without breaking the overall hierarchy.

Key principles:

• Bifrost-based computational core
• Modular architecture
• Non-destructive assembly
• Performance optimization

The presented Spine module includes:
• Stretch / Compression system
• Volume / Volume Center control
• Adaptive volume redistribution
• Procedural deformation logic

More to come.

[RUS] Более года я разрабатываю NebulaRig — модульную систему авторига, построенную на базе Bifrost.

Основная цель проекта — создать максимально производительный и гибкий риг, способный масштабироваться под разные задачи: от кино до real-time пайплайна.

В основе системы лежит вычислительная архитектура Bifrost, обеспечивающая процедурную логику, стабильность расчётов и чистое разделение компонентов.

NebulaRig состоит из независимых модулей, соединённых через систему Guide Points (GP).
Такой подход позволяет подключать, перестраивать и расширять структуру без разрушения общей иерархии.

Ключевые принципы:

• Bifrost-based вычислительное ядро
• Модульная архитектура
• Неразрушаемая сборка
• Оптимизация под производительность

В представленном модуле Spine реализованы:
• Stretch / Compression система
• Контроль Volume / Volume Center
• Адаптивное перераспределение объёма
• Процедурная логика деформации

Продолжение следует.

Hi! I’d like to introduce my custom 100% Bifrost limb solver.
It includes the following features:

FK and IK
Soft IK (Adjusts the interpolation of movement. The IK fully extends when the IK handle reaches zero.)
Stretch
Shoulder/Elbow Length Adjustment
Shoulder/Elbow Offset Adjustment
Pole Vector
Pole Vector Follow (Tracks the IK handle for smoother control.)
Pole Vector Snap
Seamless FK/IK Switch (Works seamlessly with controller positions and limb length.)

View Instagram Stories in Secret

The Instagram Story Viewer is an easy tool that lets you secretly watch and save Instagram stories, videos, photos, or IGTV. With this service, you can download content and enjoy it offline whenever you like. If you find something interesting on Instagram that you’d like to check out later or want to view stories while staying anonymous, our Viewer is perfect for you. Anonstories offers an excellent solution for keeping your identity hidden. Instagram first launched the Stories feature in August 2023, which was quickly adopted by other platforms due to its engaging, time-sensitive format. Stories let users share quick updates, whether photos, videos, or selfies, enhanced with text, emojis, or filters, and are visible for only 24 hours. This limited time frame creates high engagement compared to regular posts. In today’s world, Stories are one of the most popular ways to connect and communicate on social media. However, when you view a Story, the creator can see your name in their viewer list, which may be a privacy concern. What if you wish to browse Stories without being noticed? Here’s where Anonstories becomes useful. It allows you to watch public Instagram content without revealing your identity. Simply enter the username of the profile you’re curious about, and the tool will display their latest Stories. Features of Anonstories Viewer: - Anonymous Browsing: Watch Stories without showing up on the viewer list. - No Account Needed: View public content without signing up for an Instagram account. - Content Download: Save any Stories content directly to your device for offline use. - View Highlights: Access Instagram Highlights, even beyond the 24-hour window. - Repost Monitoring: Track the reposts or engagement levels on Stories for personal profiles. Limitations: - This tool works only with public accounts; private accounts remain inaccessible. Benefits: - Privacy-Friendly: Watch any Instagram content without being noticed. - Simple and Easy: No app installation or registration required. - Exclusive Tools: Download and manage content in ways Instagram doesn’t offer.
