In this chapter, you’ll continue to build on the game weapon generator you’ve created in Chapters 2 and 3 , by adding code to unwrap and generate materials for different parts of the gun. We’ll begin by using geometry nodes to create a circular bump grid, then write Python code to bake a normal map from it to build the gun grip’s shader node tree, to emulate 3D detail without the expense of actual geometry. After that, we’ll build a second geometry node tree to generate a custom cross-motif grid to bake a more complex normal map for the gun’s grip. With these two projects under your belt, you’ll have developed the skills necessary to generate normal maps for any project.

In this chapter, you’ll continue to build on the game weapon generator you’ve created in Chapters 2 and 3 , by adding code to unwrap and generate materials for different parts of the gun. We’ll begin by using geometry nodes to create a circular bump grid, then write Python code to bake a normal map from it to build the gun grip’s shader node tree, to emulate 3D detail without the expense of actual geometry. After that, we’ll build a second geometry node tree to generate a custom cross-motif grid to bake a more complex normal map for the gun’s grip. With these two projects under your belt, you’ll have developed the skills necessary to generate normal maps for any project.
