Welcome to RenderMan for Houdini 23.4!

This release of RenderMan for Houdini (RfH) 23, includes a number of new features and bug fixes that address feedback.

  • RenderMan for Houdini now supports multiple production builds of Houdini 18. Please see the required version of Houdini for 18.0 as we have updated the builds we support. 

  • Due to the changes in order to support multiple binary incompatible releases of 18.0; 23.4 will require different installation steps as linked here.

  • Rendering with RenderMan will not operate on Houdini Apprentice editions. See Side FX's website for options that allow Third Party Rendering

New Features

  • Added support for shutteroffset with packed alembic

  • Support added for point instancing from geo node (with ptinstance parameter)

  • Checkpointing can now take a sequence of intervals that it steps through with each checkpoint, this allows output at different specified timings. Please see the documentation link

Fixes

  • Fixed a bug where the manifold coordsys was not interactive

  • Fixed bug where transform motion blur was not propagated properly within subnets

  • Corrected a memory corruption bug that caused crashes with select alembic files

  • Fixed where the incorrect materials were applied to packed alembic geo

Miscellaneous Changes

  • Added a namespace argument to args2hda script

  • Added an originalCase flag to args2hdsa script to prevent shader names from converting to lower case



Reminder: Renamed Houdini velocity privmars called "v" to "vel"; as "v" is a reserved attribute for RenderMan geometry. Shaders in RenderMan for Houdini should refer to "vel" instead of "v".
