Houdini School – HS-118 – Attributes
Info:
Understanding Attributes is fundamental to successfully building projects in Houdini. In this recorded class, you will focus on building your core knowledge, demystifying Attributes, discussing how to create them, and most importantly explaining how they are integrated into Houdini. Class topics include basic Geometry components, clarification of the terminology, different creation & management methods, as well as exploration of differences between VEX, HScript, and Python. After this class, you will have a clearer understanding of how to build attributes, troubleshoot common issues, and extract the data you need for your projects.
Session 1
Foundations
This session will focus on the core foundations of understanding geometry components, what attributes actually are, their classes & types, as well as the precedence the data order takes.

Session 2
Reading, Writing, and Organization
This session will focus on what attributes are NOT, VEX, VOPs, HScript, Python, Local & Global variables, $ versus @, creation methods, writing methods available to customize your own attribute data, as well as parameter usage.

Session 3
Native Attributes
This session will focus on reviewing and using native attributes Houdini provides, and in some cases requires to perform various simulation tasks. Lots of example builds will be shown, including RBD, FLIP, Vellum, Crowds, and Viewport GL features.
