AssetBundles let you stream additional assets via the UnityWebRequest class and instantiate them at runtime.
Create AssetBundles by calling BuildPipeline.BuildAssetBundles or using the Scriptable Build Pipeline package.
A bundle built for any of the standalone platforms can only be loaded on that platform, for example a bundle build on iOS is not compatible with Android.
This is because shaders, textures and other types of data are built into platform-specific formats based on the BuildTarget.
