THE EDGE | Procedural Houdini Building Tool

I made this environment to showcase my procedural building tool.
The tool is based on multiple cubes, that get merged together and separated to roofs, walls, floors and platforms. From there on it checks for interactions between them, to create all the connections. It was my first time making a project using Houdini with a link to Unreal, and a good introduction to Substance Designer.
All the assets were made by me, except for Megascans rocks (I altered the material), decals and ivy.
Based on the concept of Roman Lutsenko: https://www.artstation.com/artwork/RnoP8X
