So I tried making the illusion of detail in my model of a medieval house. I could not achieve realism unfortunately. I also think I did an okay job on the texturing illusion. Needs a lot of work.
This is how most of my image textures look like. Two images (same image) texture coordinate for the image for the bump map, I also tried noise texture. I could not see the difference much in noise texture so I switched to image textures which I could see. I am changing the wall texture for sure it looks to repetitive and going to change the nodes once I figure out how to achieve better fake detail.
