I recorded a small fragment of work for you

What could be more fun than creating UV mapping on a 3D model? For example... anything.
  UV unwrapping is the projection of an image on the border of a 3D model. The scaling and shape of the final appearance of the textures depends on its location. To understand the principle of development, it is enough to imagine assembling a model from paper, but in the reverse order - the object is cut and unfolded into flat parts.
