I created this from a series of images I shot of the wall on my front porch. I generated a mesh using Agisoft Metashape, and then baked it into textures with Marmoset Toolbag 4. After that I used Substance Designer for de-lighting and general albedo adjusting. Finally, I went crazy with the clone tool in Substance Painter to make it tileable. The final render is from Marmoset.
