PART 21: CLOUDS I (VDB)

In this Houdini part, I break down the workflow of creating clouds and working with VDB volumes, this is the PART 20. I will cover the very basics of the clouds structure and how it works. PART 20 knowledge is necessary but if you are familiar with VDBs then it will be an easy ride for you. This is a difficult concept for beginners but I have tried to make it easy so anyone can understand clouds workflow.

Chapters:
00:00 - Intro
02:00 - Base Concept
14:10 - Clouds Shape
28:50 - Billowy Noise
54:00 - Wispy Noise
01:02:39 - Outro

You’ll learn how to:
How cloud shape works,
How primitive sphere Point calculates the radius
What affects the Point Radius
How Pscale act as Radius for the primitive sphere
The Basics of Cloud Generator Node
Willowy Noise
Wispy Noise
Advection
and more


I have created examples to explain each concept, so it wont be difficult to follow along. NOTES ALSO, explaining each concept with examples (really important the GAIN in the Billowy Noise)

If you’re learning Houdini, and want to step further with the VDBs and want to create your first render this is the perfect video for you.


What I cover:

Primitive Sphere
Point radius
Point scale radius
Noise
VDB
SDF
Cloudshape Generate SOP node
Cloud noises
and much more
