Procedural Montreal House
This is a tool made with Houdini to create Montreal type houses and is used as a digital asset in Unity using the Houdini Engine.
It has parameters to change the size of the house, the size of each modules (balconies, doors, windows, etc), their placements, the colors. The tool also allows to replace each module with external ones made in 3dsMax for example.
One of the main features is the procedural UVs of the body of the house and how they adapt to the size changes, and how the height of the modules adapt to the number of bricks on the house material.
