This Abondoned Factory [SCAN] asset have been spinning around on artstation for some time now. I've been having this scene in my library for a long time, and I got it from the Unreal marketplace when it was free. I finally got some time over to re-do the lighting in this scene. The goal was to achieve different kind of lighting scenarios (Foggy, Night and Sunny). All images is taken directly in the engine, and I only used post-process and color grading. No LUT:s, Photoshop or any other tool/program was used to improve the final image. Stay safe out there!
