BuildAssetBundleOptions.IgnoreTypeTreeChanges

Description

Ignore the type tree changes when doing the incremental build check.

This allows you to ignore the type tree changes when doing the incremental build check. With this flag set, if the included assets haven't change but type trees have changed, the target assetBundle will not be rebuilt.

//Create a folder (right click in the Assets folder and go to Create>Folder), and name it "Editor" if it doesn't already exist
//Place this script in the Editor folder

//This script creates a new Menu named "Build Asset" and new options for different Build Asset Bundle Options. Click these menu items to build an AssetBundle.
