Summary

In this chapter, we learned how to download textures and texture maps from the internet and apply them in Blender using nodes. We then learned how to create our own Roughness maps and Normal maps in Blender, with the help of GIMP. Having access to an image editing program such as GIMP is important because almost any 3D project will require some external image editing, whether it is for texture maps, custom textures, decals, or post-processing.

We also learned how to bake normal maps. This allows us to easily turn surface details into normal maps that we can apply to any material. Baking can also be used for colors and roughness, and it is a great way to convert procedural materials into savable images.

In the next chapter, we will learn how to create some common materials by using the tools and techniques that we’ve learned, combining them with some tips and tricks to make them look realistic on a 3D model.
