Creating Stunning Volumetric Clouds & Skies by Houdini by Joel Berg

This course is a practical, hands-on guide to building believable cloud environments in Houdini 20. You’ll skip the theory and jump straight into sculpting a range of cloud types, from fluffy fair-weather cumulus to menacing thunderheads, and then learn how to render them efficiently with Karma XPU and Solaris.

🎯 What you’ll learn

• Sculpt detailed volumetric clouds using Houdini 20’s new tools.
• Build and composite complete sky environments with realistic lighting.
• Render complex cloud scenes efficiently with Karma XPU and Solaris.
• Integrate your cloudscapes into film, TV, or game projects.

✅ Requirements

• Skills: Basic familiarity with Houdini’s interface and 3D concepts.
• Tools: A 3-button mouse.
• Hardware: A dedicated GPU (NVIDIA or AMD) with at least 8GB VRAM for Karma XPU.

📝 Description

This isn’t a dry lecture on atmospheric physics. It’s a focused, project-based course where you’ll get your hands dirty with Houdini 20’s new cloud tools right from the start. You’ll learn the specific workflows for sculpting different cloud types—understanding the parameters that control density, shape, and lighting.

The course then moves into environment building. You’ll see how to place your clouds into a convincing sky, using lighting and composition to create mood. The rendering section is particularly valuable, as it covers the practical realities of using Karma XPU and Solaris for volumetric effects. You’ll learn how to balance quality and render times, and how to composite your final passes in Nuke for a polished result. By the end, you’ll have a repeatable pipeline for creating any sky you can imagine.

🧑‍🎓 Who this course is for

• Houdini artists who want to add realistic cloud and sky creation to their skillset.
• VFX and environment artists looking for a practical, modern workflow for volumetric effects.
• Intermediate users who want to get the most out of Houdini 20’s new features.
