FBX Processing Tool for 3ds Max

A comprehensive MAXScript tool for batch importing, cleaning, and optimizing FBX files in 3ds Max.

Features

• Batch FBX Import: Process entire folders of FBX files with a single operation
• Smart Sorting Options: Sort files alphabetically or by size (ascending/descending)
• Automatic Scene Cleaning: Removes unnecessary objects like lights, cameras, helpers, etc.
• Material-Based Merging: Intelligently combines objects with the same material
• Memory-Optimized Processing: Adaptive batch sizing based on scene complexity
• Progress Tracking: Real-time feedback on processing status
• Multi-Stage Pipeline: Import, clean, and merge in a seamless workflow

Benefits

For Corona Renderer

• Creates optimal scene structure for proxy creation
• Streamlines material application
• Reduces scene complexity while maintaining visual fidelity

For Unreal Engine

• Prevents creation of countless duplicate materials during import
• Simplifies object positioning and manipulation
• Makes LOD implementation more straightforward
• Optimizes geometry for Nanite activation

Installation

1. Download all script files:

   • main.ms
   • cleaner.ms
   • merge.ms
   • importer.ms

2. Place all files in the same directory, preferably in your 3ds Max scripts folder.

3. Run the main script from 3ds Max by:

   fileIn "path/to/main.ms"
   

   Or create a button on your toolbar by dragging the MAXScript icon to your toolbar and assigning the script to it.

Usage

Main Interface

The main interface provides access to all tool functions:

• Import FBX Files: Launch the FBX import settings dialog
• Clean Current Scene: Remove unnecessary objects from the current scene
• Merge By Material: Merge objects by material in the current scene
• Import, Clean & Merge: Run the complete workflow

Batch Import Settings

When selecting the Import function, you can configure:

1. Import Mode:

   • Directory (Batch Import)
   • Single File

2. Sort Order:

   • Alphabetical
   • Size (Smallest First)
   • Size (Largest First)

3. Processing Options:

   • Clean scene after import
   • Merge by material after cleaning
   • Save processed files (.max)

Best Practices

• For very large datasets, sort by size (largest first) to process the most memory-intensive files when 3ds Max has the most available resources
• Enable "Save processed files" to create .max files automatically for future use
• Consider breaking extremely large imports into multiple folder batches

Technical Details

The tool consists of three main modules:

1. Cleaner Module: Removes non-essential objects and returns geometry
2. Merger Module: Combines objects with identical materials using optimized memory management
3. Importer Module: Handles FBX file importing with progress tracking and batch processing

Requirements

• 3ds Max 2018 or newer
• Sufficient RAM for handling your model complexity
