Re: walls and floors black

I Tried that also; I also tried repairing the game and changing from full-screen to window mode. ANY tips????

Try right clicking on the game in Origin and hit repair game

If that doesn't help, could you please post a picture of what you're seeing ?

this is happening to me also

Are you using any mods or cc in your game? Try to remove them and see if the game works better.
For example, move the mods folder from C:\Users\Username\Documents\Electronic Arts\The Sims 4 to your Desktop and start the game.

Open your Origin client and go to My Game Library, right-click The Sims 4 and choose Repair.
