In this tutorial, you will learn how to use the Cloud Rig tool in Houdini. This tool lets you use volumes to generate realistic clouds and cloudscapes. In both cases, you will start out with a simple box and fill it up with a volume. You will then add noise to create a puffier look. Under the surface, this tool uses the OpenVDB tools introduced with Houdini 12.5.
In this presentation from the Side Effects booth at GDC2015, product marketing manager Robert Magee explains the benefits of artists building their own tools for Unreal Engine 4. He talks about how Houdini and the Houdini Engine can be used to build procedural tools for use in the Unreal Editor.
