Blender Bridge

Blender s&box Bridge — Blender Addon Real-time bidirectional scene sync between Blender and the s&box editor. Model, transform, texture, and map from Blender directly to the s&box scene editor. Installation Requirements • Blender 5.1+ • s&box with the Blender Bridge library installed Install the Addon • Download sbox_bridge.zip from the latest release • In Blender: Edit > Preferences > Add-ons > Install from Disk • Select the downloaded sbox_bridge.zip • Enable "s&box Bridge" in the addon list Connect to s&box • Open your s&box project — the bridge server starts automatically on port 8099 • In Blender, open the N-panel (press N) > s&box tab • Set your Assets Path to your s&box project's Assets/ folder (needed for materials) • Click Connect Features • Mesh streaming — Create/edit meshes in Blender, they appear in s&box in real time • Bidirectional transforms — Move objects in either editor • Light sync — Point, Spot, and Sun lights sync between Blender and s&box • PBR materials — Principled BSDF nodes auto-generate .vmat files with textures • Chunked transfer — Large meshes (20k+ vertices) stream without freezing • Auto-reconnect — Connection recovers automatically if s&box restarts • Send to Scene — Manually push selected objects with one click • Grid alignment — Match Blender's grid to s&box units Panel Overview The addon adds an s&box tab to Blender's N-panel with: SectionDescriptionConnection | Connect/disconnect, host/port settings Grid Size | Quick buttons to match s&box grid (2, 4, 8, 16, 32) Sync | Auto Sync toggle, Scale Factor, Assets Path, Sync All / Force Resync / Send to Scene Info | Synced object count, latency, play mode indicator Pending Deletes | Confirm or cancel deletions (5-second safety window) Warnings | Unsupported feature warnings Materials | Manage generated .vmat files Supported Object Types Blender Types&box ResultNotesMesh | MeshComponent | Full geometry + per-face materials Point Light | PointLight | Color, radius Spot Light | SpotLight | Color, radius, cone angles Sun Light | DirectionalLight | Color Area Light | — | Not supported (warning shown) Curve/Surface/Meta | Mesh (auto-converted) | Converted to mesh on sync Settings SettingDefaultDescriptionHost | localhost | s&box bridge server hostname Port | 8099 | s&box bridge server port Auto Sync | On | Automatically sync scene changes Scale Factor | 1.0 | Blender-to-s&box unit multiplier Assets Path | — | Path to s&box project Assets/ folder Auto Reconnect | On | Reconnect automatically on connection loss Troubleshooting • Can't connect: Make sure the bridge server is running in s&box (Editor > Blender Bridge) • Objects don't appear: Check that Auto Sync is enabled, or use Send to Scene • Materials show pink/error: Set your Assets Path. New .vmat files need a moment to compile in s&box • Area light warning: s&box doesn't support area lights — use point or spot instead • Frozen UI on large mesh: If you hit this, the mesh exceeded the chunk threshold. Try reducing polygon count • Hammer editor might need to be open to place meshes can be closed after. • To Play a scene you might need to save (ctrl + S) the scene after editing to see geometry appear in Play mode (s&box).
