RenderMan supports the native USD "Solaris" workflows introduced in Houdini 18.  Solaris offers artists and TDs:

• Access to native USD for scene composition, variants, and overrides.  USD is a robust technology for building up assets, putting them into sets, and adding shot specific details and animation.  It is a great pipeline tool.
• A new lighting toolset that allows artists to build lights into their USD scenes.
• Direct batch rendering of USD files via Houdini's "husk" command-line renderer.

RenderMan provides a USD Hydra Renderer Delegate that allows artists to render interactively directly to the Solaris viewport.  Artists get immediate path-traced visual feedback during scene assembly, adjustments to lighting, materials, and other scene attributes.  The same RenderMan Hydra Renderer Delegate is what also allows the "husk" command-line renderer.

As the SideFX builds on Solaris, RenderMan will continue to provide deep matching integrations to new features and capabilities.
