In UV terms, each face is mapped to the 0 to 1 texture space; hence it quickly simulates a tiled look. Select the surface, go to polygon UVs > unitize option box and enable the create new UV set option. Set the name to tiles and click on apply and close. As you can see the texture map tiles perfectly to our plane surface. Now we want to add a little dirt to the texture by layering a dirt and grime map. But we want this 1k map to be applied to the entire surface rather than unitized to each face. To achieve this, select the plane, go to polygon UVs > planar mapping option box and use the create new UV set option to create a new set called dirt.
