In this example, before loading the Material from Bundle 1, you would need to load Bundle 2 into memory. Unity will not attempt to automatically load dependencies.Ĭonsider the following example, a Material in Bundle 1 references a Texture in Bundle 2: Should an AssetBundle contain a dependency, it is important that the bundles that contain those dependencies are loaded before the object you’re attempting to instantiate is loaded. If multiple objects in multiple bundles contain a reference to the same object that isn’t assigned to a bundle, every bundle that would have a dependency on that object will make its own copy of the object and package it into the built AssetBundle. In this case, a copy of the object that the bundle would be dependent on is copied into the bundle when you build the AssetBundles. A dependency does not occur if the UnityEngine.Object contains a reference to a UnityEngine.Object that is not contained in any AssetBundle. AssetBundles can become dependent on other AssetBundles if one or more of the UnityEngine.Objects contains a reference to a UnityEngine.Object located in another bundle.
