This project is heavily inspired by the Ubisoft GDC Talks. It is a tight integration of the Houdini Engine into Tool Development in Unity.
The whole system is tightly integrated into the native Unity Terrain System. the Tool takes the user inputs from the terrain like heightmaps or painting and improves those with Houdini.
The Creation of the Environment showcased here took me 15 minutes, with around 10 minutes of processing time included. This means actual worktime was around 5 minutes. Of course, the creation of a tool that makes this possible takes a lot longer.
If you have the 5 minutes to watch the video, I showcase the whole creation, sped up, of course.
