"The Unsullied" by Dylan Sisson, rendered in RenderMan for Houdini

What's New

Solaris support in Houdini 18.0

...

For those using the 18.0 (beta) of Houdini, the key feature is the new support for the RenderMan delegate in Solaris. In addition to RenderMan Hydra Delegate support with v23, RenderMan for Houdini also offers additional interactive display options, batch rendering options, RenderMan specific geometry settings, and additional advanced settings for light sources when using Solaris.

...

• Created dynamic array node that allows integer inputs. This node replaces the buildarray node that caused warnings when connected to utilityPattern of PxrSurface. .
• Added GL tags to bxdf nodes for visualization in the viewport. 
• The Houdini node path is now used as the RenderMan object identifier for rib debugging. 
• No longer propagate non-fatal rendering errors to the ROP node. RenderMan errors are now considered warnings on the ROP node.
• Initial rendering now obey crop parameters.
• Corrected NURBS surface orientation.
• Added MatteID users parameters to RenderMan spare parameter tab for easier access.
• Null node can now represent a coordsys with it's node path.
• Created sun direction handle for PxrEnvDayLight.
• Mesh light geometry no longer needs to be included in candidate lights to illuminate scene.
• A bug that prevented an auto headlight from being generated when using render region has been fixed.
• Added support vector3, vector4, matrix4x4 parameter script_ritype tags.
• Deprecated PxrManifold3DN.
• Forced matte objects are now rendered regardless of display toggle or forced object membership.
• Fixed a bug on linux where Houdini could crash if rendering to 'it' after having rendered in the Render View.
• Added "View Selected RIB" menu tool (only works in versions 17.5.229 and later).
• Simplified displacement workflow by always setting displacement bound on geometry.
• Fixed extraneous warnings created when rendering motion blur on alembic geometry imported.

• A bug that prevented the use of DWAa and DWAb EXR compressions has been addressed.

Known Issues

• Incorrect screen window when pixel aspect ratio is not 1. 
• Display edits cannot changed from the image tool to mplay.
• Cross-frame denoising pdg support.
• Phantom objects are removed from all rays, not just camera rays
• Applying undo of deleted nodes or collapsing to subnet may not work as expected
• Rewiring subnet indirect inputs
