[WHY] AssetName and AssetBundleName Problem

1. AssetName is path included ( solved )

in the thread
http://forum.unity3d.com/threads/new-assetbundle-build-system-in-unity-5-0.293975/
has a example project, it load asset by it's name, ex: cube

but in my project,
i have to load the asset by full path, is anything wrong?

file location:
Assets/BundleResources/SFX/fireEffect.prefab
AssetBundleName is set as "sfx/fireeffect" to prefab directly.

my build script:

Code (csharp):

1.  
2. string path = GetLocalBundleUrl().Replace( "file://", "" );
3. Directory.CreateDirectory(path);
4. path = EditorUtility.SaveFolderPanel("Save to", path, "" );
5.  
6. BuildPipeline.BuildAssetBundles (path, 0, EditorUserBuildSettings.activeBuildTarget );
7.  

what i suppose it should be, same as the example project:

Code (csharp):

1.  
2. AssetBundle bundle = GetBundle( "sfx/fireeffect" );
3. bundle.LoadAsset( "fireEffect" );
4.  

but it is

Code (csharp):

1.  
2. AssetBundle bundle = GetBundle( "sfx/fireeffect" );
3. bundle.LoadAsset( "Assets/BundleResources/SFX/fireEffect.prefab" );
4.  

2. why AssetBundleName can only set a lower case string?


Update: my issue 1 is cased by case-sensitive, because i built my bundles with it's name, but i have to translate to lower case when i load it because of issue 2
