Unwrapping a cylinder
We can use a similar technique when unwrapping a cylinder. Figure 7.12 shows which edges should be marked as seams on a cylinder to correctly UV-unwrap it.
Figure 7.12 – Marking seams on a cylinder
This will create a UV map, as shown in Figure 7.13.
Figure 7.13 – The UV map of a cylinder
As you can see, the UV map shows all the faces of the cylinder, unwrapped and displayed on a 2D surface. This allows us to place a texture onto this object, and the UV map will dictate how the texture is mapped on the surface.
We now know how to unwrap some simple shapes by marking their seams manually. Next, let’s look at how to correctly unwrap some more complex objects.
