EasyMesh Batch Exporter for Blender

A Blender add-on for batch exporting multiple selected mesh objects with customisable settings, including LOD generation and viewport indicators for recent exports.

Features

• Batch Export: Export multiple selected mesh objects at once.
• Multiple Formats: Supports exporting to FBX, OBJ, glTF (gltf+bin+textures), USD, and STL.
• Custom Transforms:
  • Optionally zero the object's location before export.
  • Apply custom export scale (behaviour dependent on exporter).
  • Set custom Forward and Up axes.
• Units Handling: Choose between metres and centimetres to match your target application.
• Naming Options: Add custom prefixes and suffixes to exported filenames.
• Mesh Processing:
  • Apply all existing (visible) modifiers before export.
  • Optionally triangulate meshes using different methods (Beauty, Fixed, Fixed Alternate, Shortest Diagonal).
  • Choose specific smoothing methods for formats that support them (Face, Edge, or Off).
  • Optionally generate Levels of Detail (LODs) using the Decimate modifier (creates _LOD00, _LOD01, etc. files).
  • Apply symmetry during LOD generation to maintain model symmetry.
• Advanced Texture Handling: Automatic downscaling of textures for different LOD levels to optimise file size.
• Export Indicators: Provides visual feedback in the viewport for recently exported objects (Green = fresh, Yellow = stale) and lists them in the panel.

Installation

Method 1: Blender Extensions

1. In Blender, go to Edit > Preferences....
2. Navigate to the Get Extensions tab.
3. Search for "EasyMesh Batch Exporter" and click the Install button.

You can also find the add-on directly on Blender Extensions.

Method 2: Manual Installation

1. Download the latest release .zip file from the Releases page.
2. In Blender, go to Edit > Preferences....
3. Navigate to the Get Extensions tab.
4. In the top right next to Repositories, click the ⌄ dropdown menu.
5. Choose Install from Disk... from the dropdown.
6. Navigate to where you downloaded the .zip file in step 1.
7. Select the .zip file and click Install from Disk.

Usage

1. Find the Panel: The add-on's panel appears in the 3D Viewport's Sidebar (Press N key if hidden) under the "Exporter" tab.
2. Select Objects: Select one or more mesh objects you want to export in the 3D Viewport.
3. Configure Settings: Adjust the settings in the "Batch Exporter" panel:
   • Export Path: Choose the directory where files will be saved.
   • Format: Select the desired output file format (FBX, OBJ, etc.).
   • Coordinate System: Set the Forward and Up axes according to your target application's needs.
   • Scale: Set the global export scale (if supported by the format).
   • Units: Choose between metres (Blender default) and centimetres (common in game engines).
   • Smoothing: For applicable formats, select the smoothing method (Face, Edge, or Off).
   • Zero Location: If checked, object copies will have their location set to (0,0,0) before export.
   • Triangulate: If checked, applies triangulation to the exported mesh copy. Choose the desired method and whether to preserve normals.
   • Rename File: Add optional Prefix and/or Suffix to the exported filenames.
   • Quick LODs (Optional): Check the box in the sub-panel header to enable LOD generation. Configure the number of LODs (1-4), symmetry options, and ratio for each level. Note that LOD0 is the base mesh (after base modifiers/triangulation), and subsequent LODs are generated with increasingly aggressive decimation.
4. Export: Click the "Export Selected Meshes" button.
5. Progress: Monitor the export progress in Blender's bottom status bar. Console output provides detailed logs.

Export Indicators

• After an object is successfully exported (including all its LODs if enabled), it will be marked in the viewport.
• Green: Object exported within the last minute (FRESH).
• Yellow: Object exported within the last 5 minutes (STALE).
• Normal Colour: Object export indicator has expired, or indicators were cleared.
• Visibility: To see these colours in the 3D Viewport, ensure you are in Solid display mode and that the Shading -> Color type is set to Object. [Viewport Shading Docs]
• Recent Exports Panel: A list of recently exported objects (still FRESH or STALE) appears in a sub-panel. Clicking the icon selects the object.
• Clear Indicators: The "Clear All Export Indicators" button at the bottom of the "Recent Exports" panel will immediately remove the status from all objects and restore their original viewport colours.
