Curtains - open & closed animation?
Yeah not that important I know, just a tiny quality of immersion improvement. ^_^
We can open and close the wooden-windows. And the curtains are similar in function.
I think the sunlight should be able to reach in very far through windows on morning & evenings.
Would make for nice ambient lighting if we could close the curtains then to block it.
Why else would we have them? :)
