UE4 - First (modular) environment - Questions

Dethling

Hi
After I got a lot of feedback on my applications (thanks to all of you who took the time to give me feedback), I'm working on improving my portfolio further (https://www.artstation.com/artist/dethling).

For this I'm working on my first complete environment in Unreal 4 (also improving my Unreal 4 skills at the same time^^).
For this I plan to use a modular approach which leads to my question.

I'm building some wall segments and wondering if I need to build complete blocks (including side and back even if you never see it) or if it's ok if I only build the front plane and then stick the wall moduls together in UE4.

Also if you know some good UE4 tutorials (Materials, light, special effects etc.) feel free to post them.
I'm eager to learn as much as possible about UE4

You can just build single sided geo. The main thing to consider is lighting. If there is light from behind the modules then you'll need to either apply lightblocker proxy geo or a double sided material. You might also encounter light leaks. The best thing is to do some simple tests before you commit to building the assets.
