I decided to start a "tips and tricks" album of videos. I will put in it some short video tutorials about archiviz, the way they come to my mind. They will cover specific technics about archiviz with Blender.
This one is about the use of dupliframes to make ridge tiling that are on a curved shape and vary in size, like in some japanese roofs or on the casa Batllo from Gaudi in Barcelona.
This technique may of course be used for many other things.
