Greetings from OtakuSolutions.

We are pleased to announce the Fast-Ref v1.1.0 update. (April 2, 2026)

🐛 Bug Fixes

• Biped IK Objects Retention during Character Replacement
  • Fixed an issue where Biped IK Objects (used to constrain hands or feet to objects) were lost during character replacement. The system now remembers all IK Object links and reapplies them automatically after replacement, keeping your poses intact.

⚡ Improvements

• Animation Preservation for Complex List Controllers
  • Enhanced support for advanced rigs with nested List Controllers. Each channel is now restored individually, preventing keyframe loss during replacement.
• Automatic Handle Error Repair
  • Added "Fix Reference Info" under the Edit menu. This tool automatically reconnects broken node references based on node names to resolve internal 3ds Max errors.
• Rig Info — Mirror Settings Added
  • You can now define and save custom mirror axes in the Rig Data Manager as presets.

Hello, this is OtakuSolutions.

We are releasing an urgent patch for Fast-Ref v1.0.8. (2026-03-23)

This build is a hotfix addressing a critical Link Constraint bug discovered shortly after the v1.0.7 release.

Hello, this is OtakuSolutions.

We are pleased to announce the release of Fast Ref v1.0.6.

This build is an urgent patch update addressing a critical bug in the Replace feature discovered shortly after the v1.0.5 release. We sincerely apologize for the inconvenience of frequent reinstalls.

🔧 Improvements & Bug Fixes

• Fixed Position Constraint target loss after Replace: We have fixed an issue where the targets of nodes containing a Position Constraint inside a Position List (e.g. B_Hand_Coll_FL_00) were lost after a Replace operation. The root cause was that Constraint controllers were incorrectly included in the CTRL backup process, causing their target references to become invalid.
• Controller List UI color contrast improvement: Fixed an issue where the background color of the Controller List in the Rig Data Manager appeared differently depending on the user's environment (3ds Max version, Windows theme). The background color is now explicitly fixed to display consistently across all environments.

Hello, this is OtakuSolutions.

We are pleased to announce the release of the Fast Ref v1.0.5 update.

While this build does not feature major overall changes from the previous version, we discovered a critical issue regarding the Morph controller, which is essential for the Replace function. Therefore, we have urgently proceeded with this update.

We sincerely apologize for the inconvenience caused by the frequent need for reinstallations due to our recent updates. We are committed to stabilizing the software as quickly as possible to minimize your inconvenience.

🔧 Improvements & Bug Fixes

• Fixed Morpher Key Loss Issue: Resolved an issue where keys were lost during the Replace process. Previously, if keys were placed directly on the Morpher of a Mesh/Poly, they were omitted from the backup target.
• URL Update: Changed the WEB_TEMP_URL to our official website (otakusolutions.com/en/).

Hello from OtakuSolutions. Fast Ref v1.0.4 is now live! 🎉

This update focuses on production-ready improvements, including a new Public API layer,

stronger Replace/Reload stability, and the introduction of a smartAnim (Beta) workflow.

✨ New Features

🔌 Public API Layer Added

A new Public API layer has been added, allowing you to call Fast Ref core functions without going through the UI.

This enables more flexible integration in pipeline and automation script environments.

Reference: https://docs.otakusolutions.com/fast-ref/index?lang=en

🎬 smartAnim (Beta) Backup/Restore Workflow

A smartAnim-based backup/restore flow (Beta) has been introduced for animation workflows.

📦 Rig Data Manager User Guide

🤔 What Is This?

Rig Data Manager is a feature that saves additional information to character rig files.

Once configured, it is processed automatically later, making your work much easier!

😕 Have You Ever Experienced This?

1. I wish the Fast-Ref link worked faster

2. I wish only my designated controllers' animations were restored

3. I added a reference, but the Selection Set isn't loading?

4. Fast-Ref exports automatically, but I only want to extract what I need?

5. This character needs the body and weapons extracted separately as 2 each...

✨ Rig Data Manager Solves It!

Set once → Keep using it easily!

🧩 What Are Fast-Ref / FBX / BipedPlus?

Rig Data Manager is an integrated information node shared by OtakuSolutions products.

Since each product requires different information, they are separated by module:

💡 Check only the products you use!

예시 1) Fast-Ref만 사용하는 경우
   ☑️ Fast-Ref  ☐ FBX  ☐ BipedPlus

예시 2) Fast-Ref + FBX Export 사용하는 경우
   ☑️ Fast-Ref  ☑️ FBX  ☐ BipedPlus

예시 3) 모든 기능 사용하는 경우
   ☑️ Fast-Ref  ☑️ FBX  ☑️ BipedPlus

⚠️ You don't need to check products you don't use!
Just save what you need.

📋 What Each Module Saves

1️⃣ Fast-Ref (Basic)

Information for automatic restoration when replacing references:

2️⃣ FBX Export Settings

Settings to make FBX exporting convenient:

💡 Tip: If you save the Selection Set in the rig file, you can export it the same way no matter what scene you open!

3️⃣ BipedPlus (Optional)

If you use the Reset/Mirror function:

📖 Note: Detailed information about saving initial poses and mirror settings is described separately in the BipedPlus user guide.

🎮 How to Use

Step 1: Open Rig Data Manager

Fast-Ref 메인 UI → Tools 메뉴 → Rig Data Manager

Step 2: Check Target Information

• Current File: Name of the opened .max file
• InfoNode: Whether the INFO node exists

Step 3: Validation Checklist

Inspect items that may cause issues before saving:

⚠️ Caution: The rig must be saved in T-Pose or default pose state!

Step 4: Controller List Management

Register regular controller nodes that are not Biped:

Step 5: Select Save Module List

Select the type of data to save:

Step 6: Save

• INFO Update / Save (🟢 Green): Save to INFO node
• INFO Read (🔵 Blue): Load existing data
• INFO Delete: Delete INFO node

💡 Recommended Workflow

First Save After Completing the Rig

1. 리그 작업 완료 (T-Pose 상태)
2. Rig Data Manager 열기
3. Controller List에 컨트롤러 추가 (자동 감지 또는 수동)
4. Fast-Ref 체크
5. INFO 업데이트 / 저장 클릭
6. .max 파일 저장

Add FBX Export Settings

5. FBX 저장 클릭

When Replacing References

INFO 노드 데이터를 기반으로:
- Biped 애니메이션 자동 복원
- 컨트롤러 컨스트레인 자동 복원
- 커스텀 본 애니메이션 자동 복원

❓ FAQ

Q: Where is the INFO node created?

A: It is created at the top level of the scene with the name __INFO__REFERENCE. It is in Point Helper form and does not affect rendering.

Q: What happens if I delete the INFO node?

A: Auto-analysis mode is activated and basic functions work normally. However, pre-saved settings (Selection Set, etc.) will no longer be available.

Q: What about when there are multiple characters?

A: Open each character's rig file (.max) and save the INFO node individually.

Q: Can I use it without BipedPlus?

A: Yes, of course! Just check Fast-Ref and save. BipedPlus data is optional.

Q: The UI is a bit inconvenient. Are there plans for improvement?

A: Yes, the UI was improved as of 2026.01.19, and it will become even more convenient in the next build. Even if it's inconvenient in the current version, please wait just a little. 🙏 It will be better than it is now. It's cumbersome now, but please use the current UI and we promise improvements in the next build!

📥 Installation Guide

1. Go to [My Account] → [My Products]
2. Download the file matching your 3ds Max version used with Fast-Ref
3. Drag and drop the .mzp file into 3ds Max
4. Restart 3ds Max
5. Run from top menu > OS Tools > Fast Ref

• Cause: When reinstalling Fast-Ref, user-customized FBX options were reset, causing inconvenience. This update addresses that issue.

• Fix: Even when reinstalling Fast-Ref, your previously saved FBX options (user presets) are now preserved without being reset.

• Purpose: Enhanced convenience so you can quickly restore your previous work environment without the troublesome reconfiguration process after reinstallation.

1. Background and Cause (Context)

• Required engine registration procedure: To register characters or assets in Unreal or Unity engines, FBX data extraction in the base pose state is required.
• Previous system limitation: The existing Fast-Ref system operated only based on data registered in the 'item list,' making it cumbersome to extract temporary objects not registered or data in specific states.

2. Solution

• Manual extraction feature: The function has been made more flexible so users can extract any desired object immediately without going through the item registration process.
• Navigation: Manual export can be done via [Export] → [Export Selected Objects as FBX] in the top menu.

🔍 Cause

Multiple cases were found where rig files were distributed with test animations included.

✅ Solution

Added Auto Cleanup Animation (Remove except frame 0) option

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 regular Bones
• Configurable in Tools > Options > General > Add Process
• Default: Enabled (True)

💡 Recommendations

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