1. OVERVIEW

The Autodesk 3ds Max File Import-Export addon provides seamless integration between Blender and Autodesk 3ds Max through native .max file support.
The addon uses intelligent conversion to maintain scene integrity, materials, animations, and object hierarchies during file transfer.

Key Features:

• Direct .max file import/export

• Selective asset filtering (models, lights, cameras, splines, animations)

• Automatic 3ds Max installation detection

• Drag-and-drop file support

• Comprehensive logging system

• Professional workflow integration

2. INSTALLATION

Standard Installation:

1. Download the addon .zip file

2. Open Blender → Edit > Preferences > Add-ons

3. Click Install... and select the .zip

4. Enable the addon under Autodesk 3ds Max File Import-Export

5. Configure the 3ds Max Python path (see Configuration)

Manual Installation:

1. Extract the addon into Blender’s addons folder:

   • Windows: %APPDATA%\Blender Foundation\Blender\[version]\scripts\addons\

2. Restart Blender

3. Enable the addon in Preferences > Add-ons

3. SYSTEM REQUIREMENTS

• OS: Windows 10/11 (64-bit)

• Blender: 4.2+

• 3ds Max: 2023+ (any edition)

• Python: Compatible with 3ds Max installation

• Disk Space: 50MB+ for temp files

• RAM: 4GB minimum (8GB recommended)

Notes:

• Requires a working Autodesk 3ds Max installation

• Linux/macOS are not supported

• Admin privileges may be required on first setup

4. CONFIGURATION

Initial Setup:

1. Open Preferences > Add-ons

2. Expand Autodesk 3ds Max File Import-Export settings

3. Click Auto Detect (locates 3ds Max Python path)

4. If detection fails, manually browse to:

   • C:\Program Files\Autodesk\3ds Max 2025\Python\python.exe

   • C:\Program Files\Autodesk\3ds Max 2024\bin\python.exe

Default Import Settings:

• Models (enabled)

• Lights (enabled)

• Cameras (enabled)

• Splines (enabled)

• Animations (enabled)

• Materials (enabled)

• Armatures (enabled)

• Apply X-Axis 180° Rotation (disabled)

• Apply 0.01 Scale (enabled)

5. IMPORTING 3DS MAX FILES

Method 1: File Menu

1. File > Import > Autodesk 3ds Max (.max)

2. Select .max file

3. Adjust import options

4. Click Import

Method 2: Drag & Drop

1. Drag a .max file into Blender viewport

2. Options dialog appears

3. Configure settings → OK

Import Options:

• Models, Lights, Cameras, Splines, Animations, Materials, Armatures

• X-Axis 180° Rotation (coordinate fix)

• 0.01 Scale (unit conversion)

Tips:

• Large files may take minutes

• Check System Console for progress

• Ensure free disk space

• Close heavy applications during import

6. EXPORTING TO 3DS MAX

Standard Export:

1. File > Export > Autodesk 3ds Max (.max)

2. Choose destination/filename

3. Configure export options

4. Click Export

Export Options:

• Models, Lights, Cameras, Splines, Animations

• Selection Only (optional)

Process:

1. Blender generates intermediate data

2. 3ds Max converts to .max

3. Temp files cleaned automatically

4. Final file saved

Best Practices:

• Apply transforms before export

• Use standard materials

• Test with simple scenes

• Verify exported file in 3ds Max

7. ADVANCED SETTINGS

Logging System:

• Logs stored at: Documents\blender_3dsmax_log.txt

• Includes conversion steps, errors, performance data

Cache Directory:

• Stored at: Documents\blender_3dsmax_cache\

• Auto-cleaned after operations

Performance Optimization:

• Use SSD for faster processing

• Increase virtual memory for large scenes

• Close unnecessary applications

• Monitor system resources

8. TROUBLESHOOTING

Common Issues:

• "3ds Max Python executable not found"
  → Verify installation, use Auto Detect, or set manually

• "Export failed"
  → Check object validity, unsupported types, or isolate exports

• "3ds Max script execution failed"
  → Verify installation integrity, free disk space, restart Blender/3ds Max

• "Import shows empty scene"
  → Enable filters, check file integrity, review logs

• Conversion too slow
  → Reduce scene complexity, close apps, split large scenes

• File too large
  → Optimize textures, reduce polycount, simplify animations

9. FAQ

Q: What versions of 3ds Max are supported?
A: 2020 and later (highest installed version auto-detected).

Q: Can I use this without 3ds Max installed?
A: No. A working installation is required.

Q: Are materials preserved?
A: Yes, with enabled option. Fidelity depends on material systems.

Q: What about animations?
A: Keyframes are preserved. Procedural data may need adjustments.

Q: Batch conversion supported?
A: Not yet. Files must be converted individually.

Q: Why intermediate FBX?
A: Best compatibility between Blender ↔ 3ds Max.

Q: Blender extensions compatibility?
A: Yes, includes manifest for Blender 4.2+ Extensions.
