In Part 5 we will perform the final extrusion and merging between the neighbouring roofs and we will also take care of exception cases such as when two neighbour roofs are of the same direction. ![]() In Part 4 we will define the roof height levels taking into consideration the heights of its neighbours as well as adding additional platforms to account for drastic elevation differences. Part 4 A-B – Roof Height Levels & Roof Elevations To achieve a “stepped roofs” look, we will break the roof into a procedural pattern, where elements are assigned roof directions relative to its neighbours. In Part 3 we will start creating our roof system by using the base silhouette we created earlier. Part 3 A-B – Roof Division & Roof Direction In Part 2 we will deal with self-intersection of the stacked geometry we created in Part 1 as well as we will break the modularity of our silhouette by adding extra rules. Part 2 – Self-intersection & Offset Modularity In Part 1 we will create a network that generates the base for the building’s silhouette by writing simple rules that determine the positioning of the box geometry relative to each other. ![]() We will determine the rules for both the body and the roof and define the relationships between those elements. In the first chapter, we will focus on setting up the main silhouette and base attributes, which will be the core for driving all the following aspects of our procedural building. If you never used VEX before, make sure to check the official documentation on VEX before starting. I will expect of you to have a good knowledge of Houdini user interface as well as some basic knowledge of VEX. All the assets and files you will need for this tutorial will be included together with the course material. ![]() I will walk you through all the core concepts that are used to make this possible, which will give you a good foundation that you can apply in any other project. By the end of the series, you will be able to create the base silhouette, define relationships between various elements, procedurally place modules, generate additional geometry to give the building a finished look and create all the needed shaders that will be driven by the system. We will implement a set of rules that is flexible enough to support complex silhouettes and relations as well as we will cover the usage of both pre-made modules and procedurally generated content. In these tutorial series, we will be creating procedural lake houses in Houdini all the way from generating the main silhouette to creating the final shaders and placing setdressing.
