2: Biomes - Procedurally Generate Masks from Real Terrain Data using LIDAR and Houdini

The second video in my Landscape series, this time looking at the fastest way to extract high quality terrain layer textures, otherwise known as Weightmaps or Splatmaps, from real world heightmap data.

Whether you create your own terrain material, or source one from the marketplace or elsewhere, Terrain Layer Weight maps are a necessary step when it comes to texturing your terrain. As they create an appearance of complexity and naturalism, which can not easily be achieved with hand-painting or terrain-auto materials alone.

This is not a terrain material tutorial. Terrain materials will be the subject of a future tutorial.
