My house appears bright as if a wall is missing

@SheriGR it took me quite a while to even get the first ss on the first post and idk why but i can assure u, my mods ARE enabled and my Graphics setting going from top left to down left to top right, bottom left are all customed cuz my PC isn't suitable for games so it took a while for my PC to get used to Sims, the options go high, high, very high, high, high, high, high, and the three options checked on the last options
