Method SubAssetKey
SubAssetKey(string, string)
The address of an object inside an asset: Assets/…/Drink Potion.fbx[Drink Potion].
A sub-asset is a content entry like any other under this key, which is why sub-asset lookup has no loading path of its own any more. The bracket is not new to this file either: RequireSubAsset<T>(string, string) has always built its error address this way, and it is what the declaration writes for a clip entry.
