Chapter 8. UV Unwrapping

In this chapter, we’ll UV unwrap the models created so far (where necessary). UV unwrapping describes the process of creating a set of 2D coordinates for the faces of a model, which we can then use to apply textures to the model. Creating UV coordinates is akin to cutting up the surface of your model (along lines called seams) and spreading it out flat (see Figure 8-1). As you know, a mesh in Blender is made up of vertices joined together to form edges and faces. Each vertex in a model has its own set of spatial coordinates in the three spatial dimensions of the 3D Viewport: x, y, and z. These coordinates determine its position in 3D space. Similarly, UV coordinates are a separate set of 2D coordinates for the points ...
