Thank you :)
I usualy work in UE5, this was my first time working in UE4 (4.23 same su you).
And as for the lights, honestly, I did the same as you. Just backed lights for production and it worked. Maybe in your case the problem isindirect light settings or Post process?
BTW i played you game "Murky Gloom" and i like it. It reminds me of resident evil and i loveeee resident evil :)
TY for playing our game i appreciate it!
