I’m from Infinity Mask which is an indie team of experts from game and movie industry.
I just made a video about non realistic interior lighting in UE5 and showed a few tricks, some of them are exclusive to UE5 but you can do the rest in UE4 too.
I compared Lumen reflection to other types too.
There are also some very simple examples of materials to show how easy and simple it is to make the objects look better.
Working with post process and height fog are a part of this video.
You may achieve same results with different parameter values.
Feel free to give me any kind of feedback, if you want to know who we are you can check this video
Thanks in advance.
