Good day, I want to get a more realistic rendering in my project. As you can see from the picture, there is not much realism in the exterior coatings and exterior paint of the building. I know that there is a need for a file like a bump file to emboss keystone and cubestone, but I could not find this file in the program. Could you please help to increase the realism. How can I get more realistic results in keystone, cubestone, column coating and exterior paint?
