Smart projections is the tool that allows us to create fast UV layouts and unfold a mesh with only a few mouse clicks. To use the tool, select a 3D mesh model and change the work mode to the edit mode. All operations that use UV mapping of a 3D model are created in a window called UV/Image Editor. Create a new window in the Blender 3D interface, and change the window type to UV/Image Editor.
After opening the UV/Image Editor window and setting the work mode to edit, select all objects of the 3D model, such as vertices, edges, or faces, and press the U key. It will open the Unwrap menu with several options.
In this menu, we will find the Unwrap (smart projections) tool at the bottom.
If we choose the smart projections tool, a new menu will appear. In this menu, we can choose several options to control the way in which all projections are created. It's not as flexible as working with seams, but with this option, a few aspects of the tool can be controlled.
