Common Components

Specific Fixes for RenderMan for Houdini

Fixes & Features 

RenderMan in Houdini

• A a crash that would sometimes occur when compiling an OSL shader using PxrOSL has been addressed.

• Fixed

  a

  bug

  where

  adding

  spare

  params

  would

  appear

  to

  fail

  when

  other

  custom

  parameters

  had

  already

  been

  added.

  add support for batch rendering thru LocalQueue and
    Tractor via hbatch when using Solaris, in the Tractor Spool panel.

• Fixed

  binary

  RIB

  exports

  of

  VDB

  volumes.

• String

  parameters

  on

  VOPs

  can

  now

  be

  promoted

  if

  parameter

  is

  connectable.

  Fixed an issue where changing the render purpose in the Solaris viewport (eg. Final vs Preview) would cause all the representations of geometry to be present in
  the
        render at the same time.
  

  Changed RenderMan prototype attributes on the "Render Geometry Settings" node to have the additional "ri:attributes" namespace.  This
  allows them to be used by other consumers of USD more easily.

  Added support for PRMAN_OSL_BEFORE_RIXPLUGINS environment variable when running the RenderMan hydra delegate.

  Fixed a bug where husk renders would only render the first render product even if multiple were refereced by render settings.

  RfH will now automatically add the string "variance" to
    the beauty pass when denoise is turned on. This is required if AOV's are also
    requested to be denoised. 

  Fixed a bug where husk from houdini 19.0 wouldn't load the RenderMan plug-in on linux unless LD_LIBRARY_PATH was set to $HFS/dsolib

  connectable.
