Lighting looks weird and unnatural,Lighting looking unnatural and cutting off

Im making a horror game and these lighting issues keep occurring between walls. Each wall is a duplicate and the lighting issue makes it look very unnatural and ruins the game. Hopefully there is a fix for this weird lighting issue.

,So I’m making a horror game and theres lots of cuts between walls where the lighting looks different. Each wall is a duplicate of the other wall, it ruins that game as it looks messy and bad in general. Do any of you have a fix for why this weird lighting issue is occurring?

Maybe build the game and see how it runs then?

I built the game and the lighting changes are still an issue
