Figure 5.19 - PBR material with maps

With the Normal Map Node, it is possible to control the direction of your

Bump. For instance, using negative values will invert the ridges created

by the map. Change the Strength value to control the height of a normal

map.

You can also add tilling control to the PBR material with the Texture

Coordinate and Mapping. Connect the Mapping to each one of the

Image Textures for full control (Figure 5.20).
