To illustrate, let's add our existing base render to the V-Ray frame buffer's history list, and then basically swap some of our scene materials around. With the floor geometry selected, let's jump into the materials tab in the properties panel and add the existing light gray material to it. Then after selecting wall geometry, assign the floor material.
