USD in Houdini 19.5

Class Listing

#### Class 1: Creating Assets

In this class, we will go over some of the general updates introduced to Solaris. Afterward, we will focus on asset creation by looking at the new Reference and Asset Reference nodes and updating the project files with these new nodes. This class is a follow-up to classes 5 and 6 from HOU221. We are also going to cover the Component Builder to simplify the creation of assets and look at how we can use it with a variety of assets.

#### Class 2: Shot Workflows

This class is a follow-up of classes 7 to 10 from HOU221 where we will look at the new LOP Import and Unpack USD nodes and how they are used with the new auto collections. We will revisit the FX and Layout layers and introduce the new Layout node and how it can work with the Component Builder from the previous class.

#### Class 3: Karma Updates

Karma CPU was finally released for production and Karma XPU moved from Alpha to Beta. This class will cover the updates and current limitations of both renderers and is a follow-up to class 11 from HOU221. We will go over AOVs, Cryptomatte, Deep Camera Maps, new motion blur nodes, and render-time procedurals.

#### Class 4: MaterialX

This last class will go over MaterialX, the new open source shading network that was added to Houdini 19.0 and allows you to create shaders that are portable between different renderers and programs. MaterialX is the future of shaders in Karma, so we are going to update our assets to use MaterialX and also add USD Preview Surface to make them as portable as possible.
