Houdini Main Changelogs

Houdini 18.0.531 Fixed a bug introduced by a fix in 18.0.367 to the showing of the current SOP by volatile states when in Show Current Operator mode that caused the volatile view state to incorrectly show the current SOP geometry when in the Paint Color state with "Paint with Display Node" enabled. Tue. July 21, 2020
Houdini 18.0.531 Unity plugin: Added support for loading instance source geometry from Resources/ path which is faster than using Assets/ path. So when specifying the prefab path with "unity_instance" attribute, the plugin will now load prefabs under Resources, by specifying its Resources/ path, or simply its file name without extension. Tue. July 21, 2020
Houdini 18.0.531 The crowd solver's Drag parameter (which applies only to states with in-place animation) is now off by default. This had produced some confusion since it would cause agents to slow down from their initial velocities. Tue. July 21, 2020
Houdini 18.0.531 The Crowd Trigger DOP's particle attribute lookup trigger now supports array attributes. Tue. July 21, 2020
Houdini 18.0.531 Added a new trigger type to the Crowd Trigger DOP, which compares against the number of times the agent's animation clip has looped around. The `cliplooped` attribute created by the crowd solver now stores the number of times the clip has looped, rather than just a 0 or 1 indicating whether it's looped at least once. Tue. July 21, 2020
Houdini 18.0.531 The Copy to Points SOP will properly copy attribute values when it is recooked with a different source geometry with matching topology and in the packed primitive copy mode. Tue. July 21, 2020
Houdini 18.0.531 The Sweep SOP now generates warnings if it failed to generate a curve due to bad variant ids or degenerate curves. Tue. July 21, 2020
Houdini 18.0.530 Added support for negative values to In-Process Scheduler Mon. July 20, 2020
Houdini 18.0.530 Fixes bug that caused the license usage exporter to fail when exporting user information. Mon. July 20, 2020
Houdini 18.0.530 Agent Vellum Unpack now supports point attachment constraints (i.e. rewiring the `target_pt` constraint attribute to reference the correct point on the unpacked geometry). Mon. July 20, 2020
Houdini 18.0.530 Mantra can now properly handle multi-line comments when saving EXR files. Mon. July 20, 2020
Houdini 18.0.530 Crowd terrain projection now supports interpolating a point or vertex N attribute on the terrain geometry to obtain a smooth normal. Mon. July 20, 2020
Houdini 18.0.530 The Resample SOP in subdivide curves or interpolated curves mode will now properly interpolate group and integer attributes. Mon. July 20, 2020
Houdini 18.0.529 Corrected documentation for hou.ui.openTypePropertiesDialog(). Sun. July 19, 2020
Houdini 18.0.528 Fixed a bug where Tractor sub tasks could be run after a cancel. Job is now interrupted instead of killed. Sat. July 18, 2020
Houdini 18.0.527 re_findall will no longer crash when it matches an empty group. Fri. July 17, 2020
Houdini 18.0.527 Sequence Blend and Blend Shape SOPs should no longer get stuck with their old point or primitive id matching values. Fri. July 17, 2020
Houdini 18.0.527 Fixd an issue where the Crowd Transition DOP could read from the wrong trigger attribute name if the Fuzzy Logic Output toggle on the trigger was turned on before switching to a trigger type where fuzzy logic output is disabled. Fri. July 17, 2020
Houdini 18.0.527 Painting on very small objects with Attribute Paint should properly detect the brush intersection. Fri. July 17, 2020
Houdini 18.0.527 Added new function `maxThreads` to pdg.SchedulerBase. This should be used to determine the number of CPU cores available to Houdini. Fri. July 17, 2020
Houdini 18.0.526 HDA Processor will no longer automatically set the "Number of Inputs" parameter if the number of inputs on the HDA is greater than 100. Thu. July 16, 2020
