    Resolution Note:

    Unfortunately this was in fact a breaking architectural change between 5.6 and 2017. We will not be resolving this architectural issue.

    The extraction of source assets from an AssetBundle is not something we support in the editor. This functionality was meant to build platform specific runtime assets, as documented here: https://docs.unity3d.com/Manual/AssetBundlesIntro.html (“An AssetBundle is an archive file that contains platform-specific non-code Assets”), but not to the inverse. Once the AssetBundle is built, there is a lot of information that is lost that cannot be re-extracted properly, at least not with any tooling that we know of. The sources assets are required to solve this problem.
