It appears as though there are a lot of people struggling with learning multiple programs. For people creating games they need to know a DCC program (such as Max/Blender etc) and UE. For design professionals, they need a program to produce models and drawings.
UE’s new Mesh Modelling is a fantastic step forward. If it eventually enables people to create and share their own Mesh modifiers (like Tissue for Blender etc.) using Blueprints then it will really take off and people making games will not need DCC programs.
For Epic to achieve world domination they could give UE the ability to produce drawings from the meshes created in UE. There really is an army (many times more people than creating games and product visualizations combined) of people making products (from cups to cars to buildings) that would love to use UE to model and produce drawings. I appreciate that it is a horrible task to allow UE to create drawings but I do believe that it would be a total game-changer. A lot of people (myself included) are fed up with how expensive CAD programs are and would love to learn just one main program for day-to-day work.
