(Blender) Volucris FBX Exporter

Volucris FBX Exporter (Early Access)

A Blender 5.0+ addon that lets you export hundreds of meshes to FBX fast, clean, and consistent — without the endless manual origin fixes and back-and-forth testing in Unreal or Unity. 

With one click, addon automatically places each mesh’s origin exactly where you want it (Geometry Median, Bottom Center, or Top Center) and moves the object to world origin. Then you can use the built-in Roundtrip Preview to instantly see how meshes will look after import — before you ever export the real files.

No more fixing the same mistakes 50 times.

Just clean, production-ready FBX files in a fraction of time. 

I built this because I was tired of the same repetitive workflow every day, and now I genuinely can’t imagine working without it.

📦Assets & Bundle Export

Export each mesh as its own FBX file in one click or export an entire selection of meshes into a single FBX file. Objects are automatically duplicated and processed — your scene is never permanently modified. Supports collection-based subfolder organization so your export directory mirrors your Blender hierarchy.

🟠Automatic Origin Placement

Before export, each mesh can have its origin automatically repositioned to one of three positions — Geometry Median, Bottom Center, or Top Center — then moved precisely to world (0,0,0). Essential for game-dev workflows where pivot placement matters, and you need a fast preview or maybe even good enough result.

🔍Roundtrip Preview 

Before committing to an export, preview exactly what the FBX will look like after import — origins, smoothing, textures and all. The preview is non-destructive and fully reversible with one click. Preview layout is also configurable: import everything in one place, arrange in a line, or spread across a grid. All inside preferences panel.

(Recommended limit per preview is 50 object at once. Using more risk significant memory use, and, finally, computer freezing (max. 200))

✔️FBX Preset Support

Load any saved Blender FBX export preset directly from the panel, or use fully custom settings. Smoothing can be overridden per-export: Normals Only, Face or Edge.

📝Addon Preferences

Set a global default export path that persists across all .blend files. Configure maximum object count for previews and set their spacing if needed.

🚀Roadmap:

• Best and only reliable preview mode in Blender community
• LOD support
• Deeply customizable naming
• Batch material slot renaming and cleanup
• File version numbering
• ...aaand some more!

Early Access
This addon is in active development and marked as Early Access. The core features (origin placement and exporting) are stable and used daily. If you experience any problem don't hesitate to contact me directly and I will do everything possible to help you!

Code Quality & Review

• Code rewrite
• Out of Early Access

Preview (no longer 'Experimental')

• Preview is now off by default and gated behind a preference toggle — it can no longer be triggered via search menu, keymap, or script while disabled
• Removed mass scene-hiding — preview objects no longer affect visibility of existing scene content
• Preview objects are now imported offset from world origin (configurable distance and axis, directly under the Preview button in the panel and in Preferences)
• Preview objects are now renamed with an FBX_ prefix on import — making them easy to identify and manually clean up if "Clear Preview" is ever unavailable
• Temp FBX files now use unique per-run names (PID + random suffix) — two Blender instances previewing simultaneously no longer collide.
• Stale temp files from crashed sessions are swept on next addon startup

Blender Extension

• Converted addon to Extension
• If you see any problems proceed to 'Issues' tab on Github (link is inside Extension's preferences)
