With which program did you manage to take those screenshots?
It is a program that allows you to move the camera, add more lights, etc. It is called UUU (Universal Unreal Engine Unlocker) Here is the link to Unreal 4.

You can download this program but it is obsolete, in your patreon you have the latest version that I could add lights and other things, I have the latest version)

This is only paid, that is, you have to be a patreon member (I recommend that you be a member so that you have the latest version of UUU 4 and UUU5)
Both UUU4 and 5 are easy to use, they work almost all games, Here's another screenshot of me from another game using UUU 5
