To set up a PBR material, create a new material, and choose the

Principled BSDF as a shader. Add an Image Texture Node by pressing

the SHIFT+A key in the Shader Editor. You can also drag and drop the

image file from your file manager to the Shader Editor.

Dragging image files to the Shader Editor makes Blender automatically

create an Image Texture Node with that image as the source.

For the remaining Image Texture Nodes, you can select the first Texture

Node and press SHIFT+D twice. It creates two copies of the Image

Texture Node. Or drag and drop the remaining image textures to the

Shader Editor (Figure 5.17).

For this example, we are using a PBR material with a Normal map. The

Normal and Roughness maps don't affect colors, and for that reason,

you should change the color space settings to "Non-Color" (Figure 5.18).
