EasyMesh Batch Exporter
Streamlined mesh export for game development workflows.
EasyMesh Batch Exporter
A professional-grade Blender addon designed for game development workflows. Streamlines 3D asset export with game engine naming conventions, LOD hierarchy export, geometry nodes optimisation, and automatic texture management, all whilst handling massive polygon counts without crashes.
What it does
Game Engine Integration & Multi-Format Export
- Game Engine Naming Conventions: Built-in support for Unreal Engine (PascalCase), Unity (Capitalised_Words_With_Underscores), and Godot (snake_case) naming standards
- LOD Hierarchy Export: Creates structured FBX hierarchies with LOD levels for Unity/Unreal workflows (
{ObjectName}_LODGroup.fbx) - Export meshes, curves, and metaballs simultaneously with automatic mesh conversion
- Supports FBX, OBJ, glTF/GLB, USD, and STL formats with format-specific optimisations
- Individual object processing ensures each selected object gets its own LOD hierarchy (not merged)
- 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 & Geometry Nodes Support
- Geometry Nodes Optimisation: Enhanced support for complex procedural workflows with smart detection, data layer preservation, and improved instance handling
- 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
- Enhanced Metaball Support: Auto-smooth shading with 30ยฐ threshold and improved material preservation
Automatic LOD Generation & Hierarchy Export
- Creates up to 4 LOD levels using progressive decimation (faster processing and less memory usage)
- Hierarchy Export Mode: Export LODs as structured FBX hierarchies compatible with Unity and Unreal Engine LOD systems
- LOD objects properly named as
{basename}_LOD00,{basename}_LOD01, etc. within_LODGroup.fbxfiles - Preserves symmetry along X, Y, or Z axis during decimation
- Individual decimation ratios for each level (e.g., LOD1: 75%, LOD2: 50%)
- Each LOD follows the same robust processing pipeline (modifiers, triangulation, etc.)
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: Complete asset pipelines with game engine naming conventions and LOD hierarchy export for Unity/Unreal Engine
- Procedural Assets: Geometry nodes-based meshes with complex attributes and instances properly preserved during export
- Multi-Engine Projects: Switch between Godot (snake_case), Unity (Capitalised_Words), and Unreal (PascalCase) naming standards
- Professional LOD Workflows: Export ready-to-import LOD groups that seamlessly integrate with game engine LOD systems
- Architectural Visualisation: Export curves (pipes, railings) and meshes with consistent naming and scale conversion
- Organic Modelling: Enhanced metaball-based characters with auto-smooth shading and material preservation
- 3D Printing: STL export with precise scale control and unit conversion
- Asset Libraries: Organised exports with game engine specific naming and texture optimisation
The addon preserves your original files whilst creating game-ready exports, giving you full control over naming conventions, LOD structures, and quality vs. file size trade-offs across multiple industry-standard formats.
What's New
1.5.0 November 8th, 2025
EasyMesh Batch Exporter v1.5.0 ๐
๐ TLDR
v1.5.0 adds two major workflow features:
- Presets system: Save/load export configurations with built-in presets for Godot, Unity, and Unreal
- Custom presets: Create and share team export standards via JSON files
- glTF batch export: Combine multiple objects into a single file based on collection membership
- Zero breaking changes: All existing workflows remain unchanged
๐ Major New Features
๐ฏ Presets System
Save and load your export configurations instantly
Speed up your workflow with ready-to-use presets for different game engines and projects. No more manually configuring dozens of settings each time you switch projects!
Built-In Game Engine Presets
Three preconfigured presets included:
๐ค Godot Preset:
- glTF/GLB format with batch export enabled
- Snake_case naming convention
- Optimised material export for Godot's PBR workflow
- Automatic triangulation and mesh smoothing
๐ฒ Unity Preset:
- FBX format with embedded textures
- Capitalised_Words_With_Underscores naming
- Triangulation enabled for consistent rendering

This tool helps a lot,huge thanks.but I encountered a problem when using it today. I donโt know if my settings are wrong or something.When I export blender model using Easy Mesh Batch Exporter and import that fbx model into UE5๏ผBlender Version is 4.5,EasyMesh Batch Exporter Version is 1.4.0๏ผsomehow,the unit is always kept in meters.That causing my model to be very small in the engine,so I want to ask is if there is a solution.Because I tried all the settings on the units and scale panel,in the end,thank for the tool again.
The add-on works like a charm and does exactly what it claims to do, no complaints. Thanks a lot, awesome job!
