I made this material set in Substance Designer based on this concept art (https://www.artstation.com/artwork/QGXxx) by Artstation artist James Ross McNab. I've been working on these materials, including the floor tile (posted here: https://www.artstation.com/artwork/YaVvxb) for about four weeks. I had originally started this project as a trim sheet, but it worked out better to separate the wall materials from the floor material. I also took the combined version of these materials into Unreal and created some renders, check those out too! (here: https://www.artstation.com/artwork/BmLgqk)

I received some feedback that the broken version of the wallpaper needed a lot more work. It wasn't part of the original concept, but I decided that it deserved some love and attention. I did a fair bit of research about plastered lath walling and wallpaper. I'm really happy with the end result. The broken wallpaper took me about two additional weeks.
