Not yet. Had a look at it, but it seems more to be for assets in the main project and loading them in when needed. Not loading .pak at runtime and getting references to the stuff.
What you had in mind with the Asset Manager exactly? Packaging out? Loading in? Both?
Also it seems you need to work with primary assets and bundles to make use of the Asset Manager. I’m looking into this for modding and it should be possible to just create a material and package that out, load it in the other project. This must work at runtime, as we are going for mod support and multiplayer (ya know, the “I want to connect to server but I miss the mods” issue).
