Unwrapping UVs

We will now cover the UV unwrapping process that will later allow us to add textures to our objects.

Using Project From View

In order to quickly unwrap the UVs of the walls of the house, the shape and size of the wall still being accurate, we can use the Project From View method.

For this to work, we need to align the walls on the axis of the world coordinates (X, Y, Z). Indeed, we are going to make use of the angle of the 3D View of Blender to project the UVs. So, for each wall, we are going to rotate our view so that the wall that we are going to project is flat. This method only works for objects that are flat and aligned, so don't use it for organic shapes:

1. We will enter the Orthographic mode (5) and then enter the view that corresponds to the face that we want to unwrap. For instance, in order to unwrap the UV of the front wall we go into the front view (1).
2. In the Edit Mode and in the Face Mode, we will select all the polygons of the 3D model that we want to unwrap...
