This three-part Solaris series for Houdini 21 that takes you from USD fundamentals to a production-ready workflow: build a reusable Solaris scene template (import → lighting → Karma XPU render), create clean USD assets with Component Builder (variants, purpose, gallery), and integrate Megascans while standardizing materials and asset management.

What you’ll make: A reusable Solaris scene template for future projects A small USD asset library with variants and clear purpose settings A Megascans-driven lookdev setup with consistent materials

Key Topics: USD basics • Scene management in Solaris • Reusable scene template • Karma XPU rendering • Component Builder • Asset Gallery • Variants • Purpose • Importing external assets (Megascans) • Material assignments • USD asset management • Building a reusable asset library

Who it’s for: Artists moving from SOPs into Solaris/USD who want a clean, repeatable scene/asset pipeline for rendering and lookdev.

    Thanks. Excellent tutorial.

    Changing Primitive path for karmaphysicalsky from "/lights/$OS" to anything else detaches the sun from the sky, I can see that lighting in the video is changing as well. After this changing Altitude and Azimuth only changes the sky and there are no controls that changes the sun position? Is it a bug, or some quirks that can be fixed by the user?

    Hi Simon, I just tested it again in Houdini 21, and you are right! Although the hierarchy is correct, the lighting is changing. If anyone knows the reason for this, I am genuinely curious! Maybe it's a bug. I will try to study it more, thanks for the heads up!
