So it does work the way you explained it, at least for a portion of the buildings. you drop full individual block blueprints and supply all the resources and your npc’s will build it.
The confusion might be due to there also being the presence of smaller buildings that don’t work that way and also have loading screens.
Personally the weapons look a bit too small to me. I feel like there’s too much negative space between them, and they need to be bigger or there needs to be more of them (or both). Possibly even a sword/weapon backdrop sort of like the GoT throne
Great work so far though!
