Unwrapping the mesh
Now that we understand a little bit about what UV maps are, and why getting them right is important, we can learn how to actually unwrap a mesh. To unwrap a mesh, we start by marking the edges we want to split our mesh along. To do this, follow these steps:
- Start by selecting the edge we want to split. Next, press Ctrl + E to open up the Edge menu and select Mark Seam from the dropdown, as shown in Figure 4.31:
Figure 4.31 – Mark Seam option
After marking the seam, a red line should appear along the selected edge, as in Figure 4.32:
Figure 4.32 – Marked seam for unwrapping
