FXPHD – HOU222 – USD in Houdini 19.5

本课程是 HOU221：Houdini Artists 的 USD 和 LOPs 的后续课程，该课程使用 Houdini 18.5 发布。一年后，Houdini 19.5 发布，随之在 Solaris 和 Karma 中引入了很多变化。本课程将涵盖一些引入的新工作流程以及自上一课程发布以来修改的先前工作流程的更改。

建议您在完成 HOU221 后立即观看本课程，因为我们将使用相同的文件并展示 Houdini 18.5 和 19.5 之间的变化。本迷你课程中将更新的主要领域是对 Karma 的更改、使用 MaterialX 进行曲面处理的概述以及使用新的组件生成器。

第 1 课：创建资产
在这堂课中，我们将回顾介绍给 Solaris 的一些常规更新。之后，我们将通过查看新的 Reference 和 Asset Reference 节点并使用这些新节点更新项目文件来专注于资产创建。本课程是 HOU221 课程 5 和 6 的后续课程。我们还将介绍 Component Builder 以简化资产的创建，并了解我们如何将它与各种资产一起使用。

第 2 课：SHOT
工作流程 本课是 HOU221 中第 7 到 10 课的后续课程，我们将在其中了解新的 LOP 导入和解包 USD 节点以及它们如何与新的自动集合一起使用。我们将重新审视 FX 和 Layout 层，并介绍新的 Layout 节点以及它如何与上一课中的 Component Builder 一起使用。

第 3 类：KARMA 更新
Karma CPU 终于发布用于生产，并且 Karma XPU 从 Alpha 移至 Beta。本课程将涵盖两个渲染器的更新和当前限制，是 HOU221 课程 11 的后续课程。我们将介绍 AOV、Cryptomatte、深度相机贴图、新的运动模糊节点和渲染时程序。

第 4 课：MATERIALX
最后一课将介绍 MaterialX，这是添加到 Houdini 19.0 的新开源着色网络，它允许您创建可在不同渲染器和程序之间移植的着色器。MaterialX 是 Karma 着色器的未来，因此我们将更新我们的资源以使用 MaterialX 并添加 USD Preview Surface 以使其尽可能便携。

Title: FXPHD – HOU222 – USD in Houdini 19.5

Info:
This course is a follow-up of HOU221: USD and LOPs for Houdini Artists which was released using Houdini 18.5. One year later, Houdini 19.5 was released and with it, a lot of changes have been introduced in Solaris and Karma. This course will cover some of the new workflows that were introduced as well as changes in previous workflows that were modified since the last course was released.

It is recommended you watch this course right after finishing HOU221 since we will be working with the same files and showing what has changed between Houdini 18.5 and 19.5. The main areas that will be updated in this mini-course are changes to Karma, an overview of surfacing with MaterialX, and using the new Component Builder.

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.
