cgSide shows how to quickly texture a cliff face using Karma and Material X within Side FX Houdini.
cgSide has a few tutorials showing how to approach creating a cliff using procedural techniques both in modeling and surfacing. His latest has a dive into using both Houdini Karma and Material X to create textures for a cliff asset keeping the workflow procedural.
cgSide covers using the Material X node in Houdini and walks through using Karma for rendering.
The tutorial covers all the settings, but if you want to download the file with all the custom textures and the model, it’s on cgSide’s patreon.
