Hey guys. I am new on the programming, i have th UE4. And i want to create (right now) one house.
I have read…some users(here in the community,have use Modular workflow. Where am i going to donwload this?
Also, Moduar workflow is better than the Maya??(I am using Maya this days).

Modular workflow is that you build stuff out of components–like you might have a pillar, or a wall, or a door and you reuse those parts when you construct the environment. Level designers like those types of assets because they can construct many configurations from a set of parts. You would make your pieces in Maya and then place them in UE4.
You can also arrange things in Maya with your copies already set up and then use Full Scene Import to just send the whole thing into UE4:
