GLB Export Guide - Professional 3D Format Conversion

Quick Start - Convert GLB Files in 2 Steps

Click Export Button

In fullscreen mode, click the Export button (download icon) in the toolbar or press Ctrl+E.

Choose Target Format & Download

Select your desired format and click Export. Your converted file downloads automatically.

Popular Conversions:

GLB → OBJ - For wide compatibility (with MTL materials)
GLB → glTF - For multi-file preservation (JSON + BIN)
GLB → Optimized GLB - For web deployment (with compression)

Format Selection Tip: Choose OBJ for wide compatibility (partial material support), glTF for multi-file interchange, or optimized GLB for web deployment (full feature preservation with compression).

Select your desired format based on your workflow:

OBJ - For compatibility with older software
PLY - For point cloud applications
Optimized GLB - For web deployment
glTF - For multi-file preservation (JSON + BIN)

Export Your File

Click Export to begin conversion. Your file will download automatically once processing is complete.

Mobile Export

Access Export on Mobile

In fullscreen mode, tap the More button (three dots) then Export.

Select Format & Download

Choose your target format and tap Export. File saves to Downloads automatically.

Mobile Export Tips:

OBJ for widest compatibility (preserves basic materials)
Use Wi-Fi for GLB files with textures >5MB
Check Downloads app after export completes

Export Best Practices by Workflow

CAD Integration Workflow (GLB to OBJ)

CAD Software Integration

Convert to: OBJ

Geometry is preserved; materials are partially preserved via MTL
Widely supported by DCC and many CAD tools

Multi-Color/Material Printing

Convert to: OBJ with MTL

Preserves material assignments
Some color information retained
Compatible with advanced slicers

Game Engine Import

Keep as: Optimized GLB

Unity and Unreal support GLB directly
All materials and animations preserved
Apply Draco compression for smaller files

CAD Software Import

Convert to: OBJ

OBJ for designs needing material references
Check your CAD software's preferred format

Export Troubleshooting

Common Export Issues

Export Button Grayed Out

Quick Fix: Wait for GLB model to fully load (including textures)

Troubleshooting Steps:

Ensure GLB file loaded completely with all assets
Check if animations are still loading
Verify browser WebGL 2.0 support
Try Chrome/Edge for best performance

Export Fails or Takes Too Long

Immediate Solutions:

Free up memory - Close other tabs and applications
Choose simpler format - OBJ/PLY may export faster than formats with materials
Check file complexity - Models with many textures take longer

Advanced Troubleshooting:

For large GLB files, try exporting to OBJ or optimized GLB first
Clear browser cache if exports consistently fail
Disable extensions that might interfere with downloads

Exported File Not Downloading

Download Issues:

Check Downloads folder for the exported file
Verify browser download permissions
Try a different export format
Disable download managers that might interfere

Export Quality Issues

Common Problems:

Missing textures in OBJ: Textures are referenced, not embedded
Animation not exported: Only GLB/glTF formats preserve animations
Wrong scale: Check unit settings in your target software

Export Note: The system converts from the currently loaded GLB model. Materials and textures are only preserved in formats that support them (OBJ partial). For full preservation, use optimized GLB export or glTF.

Workflow Integration Guide

Workflow	Recommended Format	Reason
Web Deployment	Optimized GLB	Draco compression, fast loading
Game Development	GLB	Materials, animations preserved
CAD Workflows	OBJ	Widely supported mesh exchange
Archive/Backup	Original GLB	Preserves all data
Cross-Platform	OBJ with MTL	Wide compatibility

Export Best Practices

Pre-Export Optimization

Prepare Your GLB Model

Check textures: Ensure all textures are embedded and optimized
Verify materials: Confirm PBR materials display correctly
Test animations: Play through all animations if present
Optimize size: Apply Draco compression if re-exporting GLB

Choose the Right Format

Preserve everything: Use optimized GLB
Wide compatibility: Export to OBJ with materials
Multi-file pipelines: Use glTF (JSON + BIN)
Point clouds: Use PLY with vertex colors

Verify Export Quality

Test in target software: Import exported file immediately
Check feature preservation: Verify materials/textures if expected
Validate geometry: Ensure no missing or corrupted meshes
Confirm scale: Check units in destination application

Export Implementation

Multi-Format ExportDialog Component

The export functionality is implemented through the ExportDialog component (src/components/glb-viewer/fullscreen/ExportDialog.tsx), supporting multiple formats:

// Multi-format export functionality
const handleExport = useCallback(async () => {
  if (!online3DViewerAPI?.exportModel) {
    return;
  }
  
  // Format selection based on target workflow
  await online3DViewerAPI.exportModel(
    formatConfig.fileFormat,   // 'Binary' | 'Text'
    formatConfig.extension     // 'obj' | 'ply' | 'off' | 'gltf' | 'glb' | '3dm' | 'bim'
  );
}, [selectedFormat, formatOptions, online3DViewerAPI]);

Format Conversion Pipeline

The system provides intelligent format conversion:

Geometry Preservation: All formats maintain mesh integrity
Material Handling: Smart downgrade for formats without material support
Texture Management: Embedding or referencing based on format capabilities
Optimization: Automatic compression and size reduction where applicable

Performance Optimizations

Memory Management: Efficient handling of large GLB files with textures
Streaming Export: Progressive processing for large models
Format-Specific Optimization: Each format uses optimal encoding
Browser Compatibility: Works across all modern browsers with WebGL 2.0

Next Steps

After mastering GLB export:

Learn measurement tools for analyzing model dimensions
Explore material inspector for PBR material management
Check troubleshooting for format-specific solutions
Review mobile guide for mobile export capabilities

Professional Workflows

Game Asset Pipeline: Direct GLB support in Unity and Unreal Engine
CAD Integration: Automated GLB to OBJ conversion or neutral exchange for engineering workflows
Web Optimization: Draco compression and texture optimization
Cross-Platform Compatibility: Export to the right format for any software
