📦 Rig Data Manager User Guide
📦 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!
Before
After
Manually restore animations after replacing reference
✅ Automatic Restoration
Manually select nodes every time FBX Export
✅ Use Saved Selection Set
Manage Selection Set separately for each scene
✅ Saved Together in Rig File
Must remember constraint information
✅ Automatically Reconnected
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:

Product
Description
Fast-Ref
Fast-Ref
Information required for reference system
FBX
Fast-Ref (FBX Export function)
FBX export settings
BipedPlus
BipedPlus
Information required for Reset/Mirror functions
💡 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

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

❓ 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!

Bug Fix

FBX Export Option Preservation Improvement
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.

FBX Manual / Selection Export Added
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.

Auto Cleanup Animation
🔍 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.
