One of the most fun parts of playing around and creating scenes in Unreal is that sometimes I have a really strong idea of what I want to do and it's almost planned out in my head shot by shot. And sometimes, like with this scene, I'm just making up shots and ideas as a go along, based on a very loose idea of the vibe I'm going for.
I wanted to model a Sci Fi hallway with moving things, because I really suck at animation and I wanted something robotic to move so I could have some more movement in my scenes. And then after creating the hallway, I went on sketchfab and gathered a lot of free-to-use freaky looking creatures with animation and put them in the red light version of the hallway. This was absolutely a lot of fun and I think the lighting and atmosphere (which is what I'm always most passionate about) really turned out well :)
