For this environment, I created an abandoned apartment complex in 11 days from a photo reference, focusing on realism, set dressing, and lighting. I modeled the main assets in Blender, textured using trim sheets I made in Substance Designer, and set dressed with assets from Megascans in Unreal Engine. (The ground, trash, and groundcover plants.) Reference: https://www.flickr.com/photos/moreska/12165483465/in/album-72157644376537369/
