I know right? You can always use walls and disable the "cast shadow" option.
The real downside is that the gameplay is focused inside the sub most of the time, but sometimes peaking outside through glass can help understand what is going on but also break the core concept of Barotrauma's theme.
If the issue is wall health you can always increase its value as a compensation.

I'm pretty sure you know all this, but who knows, it might help some visitors.

Well we are more than a third through campaign with Dynamic Europa and Barotraumatic on. It's been fine so far. Glass, not as crazy as I thought it would be.

I wish this was a test drive video

Surely another great submarine to add to your collection, like the other ones you made.
