Yosemite Valley - Procedural Landscape

The setup for this landscape consists out of 5 HDAs:

1. The Terrain Load HDA loads in the cache file of the terrain from Houdini into Unreal Engine.

2. The River Tool HDA gives the artist the possibility to created a river in Unreal Engine with plenty of adjustable parameters.

3. The Cliff Tool HDA generates cliff meshes with tri-planar materials in Unreal Engine based on the slope of the mountains.

4. The Layer Allocation System HDA assigns the correct materials and grass types to each landscape layer and blends these nicely using real-time virtual textures.

5. Finally, the Object Spawner HDA lets the artist input tree meshes and adjust their parameters so that the landscape gets populated by these trees, bushes, mushrooms, etc.

All used models and textures are downloaded for free from the Quixel Megascans library.
