BipedPlus v2.0.1 Update Notes (2026-06-15)

Hello, this is OtakuSolutions.

This update migrates user data to a dedicated storage to safely preserve settings during reinstallation. It also introduces a multilingual guidance system for inch unit environments while fixing posture mirroring bugs and preset malfunctions to significantly improve production stability.

✨ New Features

1. User Data Migration to Dedicated Storage

App settings, presets, window positions, and color palettes are safely migrated to a dedicated storage directory. Data copies automatically on the first run and remains intact even after reinstallation.

2. Multilingual System Reorganization

Separated translation logic into functional modules to improve efficiency. Missing text due to language pack errors will now automatically fallback to English.

3. Inch Unit Work Environment Guidance Added

Provides a 4-language prompt asking whether to switch to centimeters when opening the tool for the first time in an inch unit scene such as in 3ds Max 2027. This prompt appears once per session and declining it preserves the existing unit.

Fast-Ref v1.2.3 Update (2026-05-24)

Hello, OtakuSolutions here.

Fast-Ref v1.2.3 is now available.

This update focuses on improving the convenience of license authentication and device registration, and greatly strengthening work environment stability during Reload.

We've made improvements so you can focus on your work without hassle in a smooth, stable environment.

✨ Key Updates & Improvements

1. [New Feature] Auto device registration & smooth guidance flow after license authentication

After completing license authentication, the system smartly detects the registration status of your PC and kindly guides you to the next step without hassle.

• Auto status detection & activation: If the current PC is already registered, the latest license info is automatically loaded and activated immediately without any additional steps.
• One-click device registration: If there's an available registration slot, a confirmation dialog "Would you like to register this computer to your license?" appears. Clicking 'Yes' activates the device with one click without needing to visit a device management web page. ('Later' is also available to register at a future opportunity.)
• Intuitive over-limit guidance: When the device limit is exceeded, a detailed guidance notification clearly explains the situation and flexibly maintains the device management screen, helping users easily decide to clean up devices.
• Full multilingual support: Supports 4 languages — Korean, English, Japanese, and Chinese — so any overseas artist or user in a different language environment can understand and use the guidance without inconvenience.

2. [Improvement] Prevention of display distortion during Reload

When reloading references from the source file, Safe Mode automatically activates to protect the work environment.

• Auto Safe Mode transition: During Reload, Safe Mode transitions run automatically beforehand to prevent scene movement, space distortion, unpack issues, etc. from being lost or misaligned.
• Viewport viewpoint recovery: The viewport viewpoint (position and view mode) you were working in is temporarily memorized and naturally restored to the original viewpoint right after Reload completes.
• 100% safe recovery system: Even if a system crash occurs during Reload, the viewport or alignment state is not damaged and safely recovers to the original work environment.
• Accidental operation prevention: When Smart Switch is off, a confirmation popup is shown first to fundamentally prevent accidental operations.

3. [UI/UX] Console log simplification for better workspace readability

Improved system log output to maintain a more comfortable work environment.

• Log simplification: Detailed system logs from the update notification feature no longer flood the 3ds Max console window.
• Readability: Only key guidance messages like errors are provided cleanly, keeping the workspace clean and comfortable.

Here's a video summarizing the updates from the past two weeks.

Fast-Ref's major improvements, BipedPlus Phase 1 beta completion, and the global payment introduction plan — all in one.

Fast-Ref — Key Changes in This Build

1. External Constraint Integration Enhanced

This build significantly improves Replace stability in scene structures built with Link, Orient, Point Constraints and other external constraints. Integration with Biped IK Objects has also been strengthened, so data that used to be lost or broken during Replace is now handled correctly. Relationship-map-based auto-linking (including bicycles, skateboards, and other Props) is also included in this improvement.

2. Smart Switch — Replace Without Namespace Conflicts

In previous versions, Replace was impossible if even one Namespace was Off — only a warning appeared. Since internal tools have no concept of Namespace, you always had to set everything to Off.

The new Smart Switch feature handles this automatically. It enables all Namespace Actives before Replace, and returns them to their original state after Replace is complete. A dialog is provided for one-click handling even without checking manually.

3. NameScope — ".r1" Suffix Removal Option Added

A new option lets you remove the .r1 suffix that was automatically added when setting Namespace to Off. Namespace On Scope and Namespace Off Scope settings allow separate control of the scope for nodes and layers.

Note: Layers don't allow duplicate names in 3ds Max, so the layer scope must remain as is. If there are duplicate layers internally, script modification may be needed.

4. Texture Relative Path Bug Fix

Fixed the issue where textures linked with relative paths in the Asset Tracking window appeared black when loading files through Fast-Ref. Additionally, the Fix Image Path feature in the Edit menu can automatically recover broken image paths.

BipedPlus — Phase 1 Beta Complete

BipedPlus Phase 1 beta testing is complete. We received a lot of feedback from beta testers. Key highlights:

• UI was too developer-centric → major improvements made
• Tutorial and educational elements lacking → incorporation in progress
• ~95% of feedback applied, build stability greatly improved

Currently aiming for official release after one or two more rounds of feedback collection.

Global Payment — Coming May 2026

Until now, individual Korean buyers could only purchase via bank transfer reservation, and corporate clients via Letter of Intent. We acknowledge the high entry barrier and are moving quickly to address it.

In May 2026 — by mid-May at the latest — global card payment will be introduced across all products including Fast-Ref and BipedPlus. Anyone from the US, Japan, China, Europe, and beyond will be able to purchase with a single card.

What OtakuSolutions Builds

We are not a plugin-selling company. Each product was built to solve specific problems that have long gone unresolved in the 3ds Max environment.

• Fast-Ref — Brings a link/reference system to 3ds Max that never existed before
• BipedPlus — Comprehensively solves Biped's long-standing limitations like Stretch/Squash, providing a Maya/Blender-level rigging environment
• SkinLayer Studio — Eliminates the pain of skinning outside Maya

You're not buying a plugin — you're buying a solution for the mission. That's why we're called OtakuSolutions.

Feedback, bug reports, and opinions on tool direction are always welcome by email. We'll respond quickly and never ignore you.

📦 Rig Data Manager Usage Guide

🤔 What is this?

Rig Data Manager is a feature that stores additional information in character rig files.

Once set up, it handles things automatically, making your workflow much easier!

😕 Have you experienced these?

1. I wish Fast-Ref linking was faster
2. I only want MY controllers to restore animation
3. I added a reference but the Selection Set isn't loading?
4. Fast-Ref auto-exports, but I want to pick only what I need
5. This character needs body and weapon extracted separately...

✨ Rig Data Manager solves all of this!

Set once → Use comfortably forever!

🧩 What are Fast-Ref / FBX / BipedPlus?

Rig Data Manager is an integrated info node shared across OtakuSolutions products.

Since each product needs different information, it is separated by module:

💡 Check only the products you use!

```plain text
Example 1) Using Fast-Ref only
☑️ Fast-Ref ☐ FBX ☐ BipedPlus

Example 2) Using Fast-Ref + FBX Export
☑️ Fast-Ref ☑️ FBX ☐ BipedPlus

Example 3) Using all features
☑️ Fast-Ref ☑️ FBX ☑️ BipedPlus
```

⚠️ You don't need to check products you don't use!

Just save what you need.

🔍 Cause

It was found that many rig files were distributed with test animation data included.

✅ Solution

Auto Cleanup Animation (Remove except frame 0) option added.

When adding a reference, if animation keys exist in the rig file, all keys except frame 0 are automatically deleted.

• Applies to both Biped and standard Bones
• Can be configured under Tools > Options > General > Add Process
• Default: Enabled (True)

💡 Recommendation

When distributing rig files, we recommend setting the default pose (T-Pose, etc.) at frame 0.

1. Background & Cause

• Required process for engine registration: Extracting FBX data in the Base Pose state is essential for registering characters or assets in Unreal or Unity engines.
• Limitations of the previous method: The old Fast-Ref system only worked based on items registered in the 'item list,' making it cumbersome to extract unregistered temporary objects or data in specific states.

2. Solution

• Manual extraction feature: Changed the function to allow users to immediately extract desired objects without going through item registration.
• Workflow: Can be executed manually via the top menu [Export] → [Extract Selected Objects as FBX].

• Cause: When Fast-Ref was reinstalled, users' custom FBX export options were reset, causing inconvenience.
• Fix: Improved so that when Fast-Ref is reinstalled, previously saved FBX options (user presets) are preserved without being reset.
• Update purpose: Enhanced usability so that the existing work environment can be quickly maintained after reinstallation without the hassle of re-configuring settings.
