Using Decals in Unity
Guide To Beautiful Games In Unity
What is Decal?
Unity can project specific Materials (decals) onto other objects in the Scene. The decals interact with the Scene’s lighting and wrap around Meshes.
You will need a HDRP Decal material to make a decal object.
When you place the object with decal material, it will bend to meet the surface needs unlike other materials which will remain as a plain.
