Houdini.School – HS-217: Noise

At the end of this course, you should have a better understanding of how to create more visually interesting noises in VOPs and VEX.
Class Description:
This recorded course takes your noise creation skills to the next level. Learn how to layer, and manipulate basic noises in order to generate exciting new patterns. All of which can be used in numerous Houdini contexts like particle emission, shader masks, volume erosion, geometry displacement, and velocity fields to name just a few.

Learning Outcomes:
At the end of this course, you should have a better understanding of how to create more visually interesting noises in VOPs and VEX.

Session 1

Intro to the World of Noise
