Unity 2.6.1 AssetBundle Export Script, builds new asset bundles + tracks dependencies

This script is a critical utility for anyone trying to export custom asset bundles with Unity 2.6.1—particularly on Mac.
It enables you to export asset bundles using Unity's old BuildPipeline.BuildAssetBundle function with full dependency tracking.

It has been structured for easy use in your Unity 2.6.1 project environment.

Instructions: How to Use in Unity 2.6.1:

1. Install Unity 2.6.1 on macOS (using a legacy environment or virtual machine if necessary).
2. Place the script in your project:
   • Create a folder named Editor inside your Assets directory.
   • Save the ExportAssetBundle.cs script in that folder.
3. Restart Unity to ensure the menu item loads properly.
4. Prepare your asset(s):
   • Drag the prefab or asset you wish to bundle into the Project window.
   • Select the asset.
5. Export the bundle:
   • Go to the Unity top bar: Assets > Build AssetBundle From Selection - Track Dependencies
   • Choose the save location and export.

This method ensures the output .unity3d file includes all referenced assets (textures, animations, etc.) required by the selected object—making it perfect for repacking FusionFall NPCs, equipment, and scenes.
