I think the railing here gives some nice detail:   And then you can do some UV mapping creativity to make the walls look not-plain.  Perhaps along the backside there can be hanging shields. 

Weird issue where everything appears in shadow. Fixes itself when changing the shadow quality while in game. Works after that until the app is restarted.  OS: Kubuntu 26.04.1 GPU: Intel Arc B580 CPU: AMD Ryzen 5 5500   The video is av1 hope that isn't an issue. Didn't want to send a massive file.

Right, my opinion as well.

@Thalatta Thanks for your research and explanation! I'll go with this one then. That was actually what I started with, but the reference doesn't help much. It's basically just two cuboids put on each other and filled up with props. It will look too empty for the 0-A.D.-style. I would need some ideas of how I could give it a more interesting shape, or add fences, windows, doors, awnings, curtains, canvas, columns etc... It's also much smaller than the corresponding stone skene in the later theaters. If we want it to be upgradeable it should have the same footprint, which means I have a lot of space to fill up. If you got ideas, let me know  I'll try to be creative (which is not my strong point :D) and then it hopefully won't be too far from historical accuracy.

Just in case, I meant when taking a screenshot. For the player to constantly see it could be optional.
