GLTF Quick Export

Standalone Blender extension for fast one-file GLB export and timed auto-export.

This repo intentionally does not include SLender's LOD management, asset tracking, validation, or Second Life-specific tooling. It is meant for creators who already have their own scene workflow and just want a repeatable GLB export target that can refresh automatically.

Features

• Manual Export Now button
• GLB-only export
• Exports either:
  • selected mesh objects
  • all mesh objects in the active scene
• Timed auto-export with interval in seconds
• Overwrites the same .glb output file each time
• Does not save the .blend
• Flushes edit-mode mesh changes before export
• Restores the previous mode after export

UI

Install

Build the extension zip:

blender --command extension build --source-dir /home/me/src/blender-gltf-quick-export --output-dir /tmp/quick-export-dist

Then install it in Blender from:

Edit > Preferences > Extensions > Install from Disk...

Development

If you want a fast local loop, symlink the repo into Blender's user extension directory and restart Blender after structural changes.

Smoke Test

Run the headless smoke suite with:

blender --background --factory-startup --python /home/me/src/blender-gltf-quick-export/tests/blender_smoke_test.py

The smoke test covers:

• manual export
• export from edit mode
• direct auto-export path

Releases

• Build Preview Extension runs on pull requests, pushes to master, and manual workflow runs.
• Preview packages are renamed to include -preview-<sha>, for example gltf_quick_export-0.1.0-preview-1a2b3c4.zip, and are uploaded only as workflow artifacts.
• Release Extension runs only when pushing a tag such as v0.1.0.
• The release workflow verifies that the tag matches version in blender_manifest.toml before publishing gltf_quick_export-0.1.0.zip to the GitHub release for that tag.
