3D Model Plugins for Blender, Unity, Unreal Engine 5 & Godot 4

Blender 4.x — Add-on

1. Download bitsoul3d-blender.zip (do not unzip).
2. Open Blender → Edit → Preferences → Add-ons → Install… and select the zip.

5. In the 3D Viewport press N to open the sidebar, click the BitSoul 3D tab, hit Refresh Catalog, pick a model, and press Import to Scene.

Tip: Imported objects spawn at the 3D cursor — set the cursor first with Shift+right-click.

Unity 2022.3 LTS+ — Editor Window

1. Download bitsoul3d-unity.zip and extract it.
2. Drag the extracted BitSoul3D folder into your project's Assets/ directory.
3. Install the glTFast package so Unity can import .glb natively:

   • Click + → Add package by name…
   • Enter com.unity.cloud.gltfast and click Add.
4. Open Window → BitSoul 3D, paste your bsm_… API key, click Verify Key.

Unreal Engine 5.3+ — Editor Plugin

1. Close the Unreal editor.
2. Download bitsoul3d-unreal.zip and extract it.
3. Copy the BitSoul3D folder into <YourProject>/Plugins/ (create the Plugins folder if it doesn't exist).
4. Reopen the project. If prompted to rebuild, click Yes.
5. Make sure these dependency plugins are enabled (Edit → Plugins):
   • Python Editor Script Plugin
   • glTF Importer
   • Interchange Framework
6. Open Window → Developer Tools → Python Console and run:

   import bitsoul3d_import as bs
   bs.set_api_key("bsm_YOUR_KEY")
   bs.list_catalog(query="castle", limit=10)
   bs.import_model("MODEL_ID_FROM_LIST")

7. Models import as Static Meshes under /Game/BitSoul3D/.

Godot 4.2+ — Editor Dock

1. Download bitsoul3d-godot.zip and extract it.
2. Copy the extracted addons/bitsoul3d/ folder into your project's addons/ directory (final path: res://addons/bitsoul3d/).
3. In Godot, open Project → Project Settings → Plugins and enable BitSoul 3D.
4. The BitSoul 3D dock appears on the right side of the editor.
5. Paste your bsm_… API key, click Save key, then Verify.
6. Click Refresh catalog and use the Import button on any row. Models save to res://BitSoul3D/ and the FileSystem dock refreshes automatically.

1. Download the zip for your OS:
   • bitsoul3d-desktop-windows.zip
   • bitsoul3d-desktop-mac.zip
   • bitsoul3d-desktop-linux.zip
2. Extract the zip to a permanent folder of your choice (e.g. Documents/BitSoul 3D). Don't move it after install — the shortcut points back to this folder.
3. Run the install script inside the extracted folder:
   • Windows: double-click Install BitSoul 3D (Windows).bat
   • macOS: double-click Install BitSoul 3D (macOS).command (if Gatekeeper blocks it, right-click → Open)
   • Linux: in a terminal run bash "Install BitSoul 3D (Linux).sh"
4. A BitSoul 3D icon appears on your Desktop / in Launchpad / in the Applications menu. Double-click it to launch the app in a chromeless window.
5. Open the Settings tab, paste your bsm_… API key, click Verify.
6. Use the Catalog tab to browse, click any model to preview it in the dock, then click Download. Files save to your standard Downloads folder.

Requirements: a Chromium-based browser (Edge, Chrome, or Brave) on Windows / macOS / Linux, or Firefox on Linux. The installer auto-detects whichever you have.

Uninstall: run the matching Uninstall BitSoul 3D script (.bat / .command / .sh) in the same folder, then delete the folder. The uninstaller removes the Desktop shortcut, Start Menu / Launchpad entry, and — if you confirm — the cached browser profile.

1. On your phone, open /marketplace/app/ in Safari (iPhone / iPad) or Chrome (Android).
2. iPhone / iPad: tap the Share button (square with up-arrow) → Add to Home Screen → Add.
3. Android: tap the browser menu (⋮) → Install app (or Add to Home screen) → Install.
4. Launch BitSoul 3D from your home screen — it opens full-screen with no browser chrome.
5. Open the Settings tab (gear icon), paste your bsm_… API key, tap Verify.
6. Use the Catalog tab to browse and the 3D Viewer tab to spin models with touch — pinch & drag to inspect. AR works via Quick Look (iOS) and Scene Viewer (Android).

Uninstall: long-press the BitSoul 3D icon on your home screen — on iPhone / iPad choose Remove App → Delete App; on Android choose Uninstall. To clear just the saved API key without deleting the app, open the app → Settings → Reset app data.
