Adding materials to the landscape

Let's add some materials to the landscape. For this, we will be using a PBR texture image consisting of the following passes:

• Albedo: Used for the Base Color
• Ambient Occlusion: For adding shadows to the Base Color
• Specular: Controls specular reflections
• Roughness: Controls the overall roughness
• Bump: For adding tiny bumps using a normal map

You can either use your own PBR materials or you can download the one we will be using here: https://github.com/PacktPublishing/Taking-Blender-to-the-Next-Level/blob/main/Chapter05/Patchy_Wild_Grass.zip

1. Before we start applying materials to our landscape, make sure you unhide the Ground object by using the show/hide eye icons in the Outliner. You can hide the mushroom model if you prefer, but it's not required.
2. Disable the Geometry Nodes modifier on the Ground object so that we don't see the grass while we're adding materials. Click the Ground object...
