qdelpeche, I’ve thought Blueprints are more like Kismet, aren’t they? As for writing such a plugin… Well, I’m not big fan of C++ and building like ANYTHING on Windows is a nightmare.
As for art, FBX/obj should remain, but import for “project” files like .blend should be added, for the diversity and because it would make easier to switch over from Unity to UE4 - just copy assets and be done.
