The decision to create an e-book dedicated to the new features of V-Ray 7 stems from a fundamental consideration: the printed version of Chiaroscuro with V-Ray remains a completely valid reference work. The new features introduced in this version, although interesting and worthy of attention, did not justify a new printed edition. An e-book, on the other hand, allows us to update the content in a specific way, while keeping the value of the main book intact, which remains a comprehensive and up-to-date guide.
