FXPHD – HOU140 – Houdini FX Tool Building 展示Houdini中复杂场景的制作方法，多个节点的控制，本课程主要针对Houdini概念（称为OTL），这是一种从其他节点中构建自己的节点的方法，通过最少的工作量，高效率制作复杂的科幻场景，我们将使用Python通过OTL的HDAModule深度控制Houdini，并研究如何利用各种特殊命名的脚本来进一步自定义Houdini处理新节点类型的方式。用传统建模方式几乎不可能完成的事情，在Houdini中可以通过SOP OTL 和Python脚本可以快速程序建模。Houdini FX Tool Building Foundation. TAUGHT BY ROBERT THOMAS.
This introductory level offering aims to get you started with a solid base of the foundations of tool building, showing how to create a complex Houdini file so that it can be run in dozens or even hundreds of shots with minimal effort in a pipeline. The course is primarily focused on a Houdini concept called OTLs, which is a way to build our own nodes out of other nodes. To that end, the course starts by making an object-level node that automatically generates emission geo from any arbitrary camera.
We’ll show how to provide hooks to users so that they can customize parts of the setup, how to create custom viewport handles, and how to improve the setup by finding inefficiencies and fixing them. We’ll use Python to control Houdini on a deep level with the OTL’s HDAModule, as well as looking at how to leverage various specially named scripts to further customize how Houdini treats our new node types.
