Types and a case study
Decals are incredibly versatile tools that can accomplish various tasks, simplifying what would have otherwise required more complex solutions. While I will focus on the main uses relevant to architectural visualization, it’s important to note that decals have many more applications in video games or interactive experiences, such as bullet holes, blood splatters, position indicators, and more.
