Houdini Main Changelogs

Houdini 18.0.351 Fixed an issue that could result in slightly incorrect transforms (often resulting in jitter) for point instancers in Houdini GL and Karma. Wed. January 15, 2020
Houdini 18.0.351 Changed topfetch and submit-as-job hython for Hqueue to use PilotPDG license if available instead of Engine. Wed. January 15, 2020
Houdini 18.0.351 Added parms for configuring work item priority to all nodes that run work items out of process. HDA Processor, Generic Generator and Attribute Create will automatically migrate their existing priority parms to the new, standard parms. This change also makes it possible to override the ROP Fetch node's built in priority scheme with custom work item priorities. Wed. January 15, 2020
Houdini 18.0.351 Changed the underlying threading isolation mechanism in Karma. This should result in slightly more efficient threading, but probably not measurable. Wed. January 15, 2020
Houdini 18.0.351 Fixed a bug with doing an RMB -> Cook Task on a batch work item, or on a work item with upstream batch dependencies. Prior to the fix, in some cases the work item would not properly cook. Wed. January 15, 2020
Houdini 18.0.351 Added new parameters to the agentsolvefbik() VEX function to specify the type (position, orientation, or both) of a target, along with an offset that can be used to e.g. align the tip of a bone with the target. Wed. January 15, 2020
Houdini 18.0.351 Packages - Add multiple path support to HOUDINI_PACKAGE_DIR
  • This fix extends HOUDINI_PACKAGE_DIR to support multiple package folders to scan.
Wed. January 15, 2020

Houdini 18.0.350 Added support for returning file results from ropfetch jobs of non-ROP nodes.

January 14, 2020

Houdini 18.0.350 Fixed a bug in UVFlatten where changing the name of the output texture attribute would only added the new attribute but kept the previously used one as well. Tue. January 14, 2020
Houdini 18.0.350 Unity plugin: Fixed multiple instance inputs where duplicate instances were being created. Fixed handle count being negative. Tue. January 14, 2020
Houdini 18.0.350 Fixed a viewport display bug where huge point clouds in DOPs could be missing some points. Tue. January 14, 2020
Houdini 18.0.350 Fixed an issue with deserialized work items incorrectly being marked as dirty on a subsequent cook. Tue. January 14, 2020

Houdini 18.0.349 Fixed an error in a change to 18.0.273 that was supposed to reduce stage traversals when generating the context menu for a USD prim. This revision actually fixes that problem. Mon. January 13, 2020
Houdini 18.0.349 RGBA textures no longer briefly show up as monochrome in the viewport when switched from an invalid to valid texture using the principled shader. Mon. January 13, 2020
Houdini 18.0.349 Added a 'Create Queue' parm to HQueue Scheduler TOP node. When set to 'Never', interactive TOP cooks will not use the Message Queue job to relay callbacks from farm jobs to Houdini. This provides a more efficient cook when the submitting Houdini is reachable by farm machines.

This does not affect the 'Submit Graph As Job' workflow.
