EasyMesh Batch Exporter

A professional-grade Blender addon that streamlines 3D asset workflows by batch exporting meshes, curves, and metaballs with automatic LOD generation, texture optimisation, and industry-standard format support, all whilst handling massive polygon counts without crashes.

What it does

Multi-Format Batch Export

• Export meshes, curves, and metaballs simultaneously
• Automatic conversion: curves and metaballs are converted to meshes during export
• Supports FBX, OBJ, glTF/GLB, USD, and STL formats
• Format-specific optimisations (Draco compression for glTF, embedded textures for GLB)
• Customisable file naming with prefixes and suffixes for organised asset libraries

Precision Transform & Coordinate Control

• Configure Forward and Up axes for different target applications (Unity, Unreal, etc.)
• Global scale adjustment with format-specific handling
• Units conversion: seamless switching between metres and centimetres
• Zero object location before export for consistent positioning
• Automatic transform application with memory-safe processing

Advanced Mesh Processing

• Modifier Control: Choose which modifiers to apply (None/Visible/Render) for performance vs. quality balance
• Triangulation: Multiple methods (Beauty, Fixed, Alternate, Shortest Diagonal) with normal preservation
• Smoothing: Format-specific smoothing options (Face, Edge, Off) for optimal results
• Memory Optimisation: Handles 2+ million polygon meshes without crashes

Automatic LOD Generation

• Creates up to 4 LOD levels using progressive decimation
• Each LOD built from the previous level (60% less memory usage)
• Preserves symmetry along X, Y, or Z axis during decimation
• Individual decimation ratios for each level (e.g., LOD1: 75%, LOD2: 50%)

Intelligent Texture Management

• Automatic Resizing: Textures scaled per LOD level (default: LOD1: 2K, LOD2: 1K, LOD3: 512px, LOD4: 256px)
• Format Preservation: Maintains PNG for alpha channels, JPEG for RGB, HDR for high dynamic range
• Normal Map Quality: Option to keep normal maps at higher resolution for visual quality
• Compression Control: Adjustable lossy compression quality (0-100%) for size optimisation
• Embed vs. External: Choose to embed textures in supported formats or save as external files
• Aspect Ratio Protection: Maintains proportions to prevent texture distortion

Export Workflow & Feedback

• Visual Indicators: Track recently exported objects with viewport colour coding
  • Green: Exported within the last minute (fresh)
  • Yellow: Exported within the last 5 minutes (stale)
• Recent Exports Panel: Interactive list of exported objects with one-click selection
• Memory Management: Automatic garbage collection for large mesh operations

Performance & Memory Optimisation

• Automatically optimises for large meshes (>500K polygons)
• Handles 2+ million polygon meshes without crashes
• Progressive cleanup every 3 modifiers during heavy operations
• Smart processing strategies based on mesh complexity

Common Use Cases

• Game Development: Asset pipelines with LODs for Unreal Engine, Unity (coordinate system presets)
• Architectural Visualisation: Export curves (pipes, railings) and meshes with consistent naming and scale conversion
• Organic Modelling: Metaball-based characters and environments with automatic mesh conversion
• 3D Printing: STL export with precise scale control and unit conversion
• Asset Libraries: Organised exports with prefix/suffix naming and texture optimisation
• Performance Optimisation: Multiple LOD levels with progressive texture downscaling

The addon preserves your original files whilst creating optimised exports, giving you full control over quality vs. file size trade-offs across multiple industry-standard formats.
