Houdini Main Changelogs

Houdini 18.0.311 Fixed a bug with erroneous rejection of constant volumes by the Volume Bound SOP. yesterday
Houdini 18.0.311 GAS Feedback DOP was changed to support using a corner-sampled pressure field in the non-weighted case. These changes could also introduce minor differences in cases where the pressure is center-sampled, such as pyro simulations with 2-way rigid body coupling. yesterday
Houdini 18.0.311 Two-way interactions between sparse pyro and rigid bodies work correctly now. yesterday
Houdini 18.0.311 Unity plugin: Added new functionality to store attributes on a new script component, called HEU_OutputAttributeStore, on generated gameobjects. See online plugin documentation under Attributes and Groups, as well as the new example asset HEUInstanceAttributeStore.hda. yesterday
Houdini 18.0.311 Dome light environment maps now use the USD-specified orientation in GL when in LOPs. yesterday
Houdini 18.0.311
  • Fixes a problem where hou.SceneViewer.setCurrentState would ignore the enter mode flag.
  • This fix allows nodeless python states to enter correctly now in supported contexts.
Houdini 18.0.311 Python State - Add point example
  • Added a new scene example to demonstrate how to write a python state for adding points in a viewport ($HH/viewer_states/example/add_point_demo.hip)
  • Added new "Add Point" sample to the Viewer State code generator.
Houdini 18.0.311 Added a new Filter by Range TOP node. This is similar to a Filter by Expression node, but it provides a higher level interface for removing work items that fall within or outside of a specified range. Work items can be filtered by their Frame, Index or a custom numeric attribute value. yesterday
Houdini 18.0.311 A case where VDB From Polygons would be indeterministic is fixed. yesterday
Houdini 18.0.311 Fixed the type for the "focal" rendering property to treat it as a 'float'. yesterday
Houdini 18.0.311 Fixed a bug with field synchronization. This bug would occasionally cause field resolutions to change. yesterday
Houdini 18.0.311 Fixed issue with OpenGL ROP where an animated camera wasn't causing view dependent prims to update (sprites, volumes). yesterday
Houdini 18.5.52 Applied a fix for bug PYSIDE-1073 to Houdini's PySide2 to avoid conflicts with the 3rd-party 'typing' Python module. yesterday
Houdini 18.0.310 Fixed issues with PDG/TOP attribute access warnings. Previously, when a node evaluated a parameter against an input work item and encountered an invalid @attribute access it would report the warning on the node that owned the input work item. This is now fixed so the warning is correctly reported on the node that's actually doing the parm evaluation. Thu. December 5, 2019
Houdini 18.0.310 Fixed a possible bug when custom HDK VEX functions accessed array variables. Thu. December 5, 2019
Houdini 18.0.310 Added support to HQueue scheduler TOP for handling non-zero exit codes. In addition to failing the job, work items can ignore, issue warnings or retry on exit codes. Also modified the job names to include the work item name. Thu. December 5, 2019
Houdini 18.0.310 Unity plugin:
  • Fixed terrain data not being generated in a certain case.
  • Allowing terrain size to be smaller than 33 units, which is separate from heightmap resolution which does need to be minimum of 33 units.
Thu. December 5, 2019
Houdini 18.0.310 Fixed a viewport material update issue when switching from the default viewport material to a real material using shop_materialpath. Thu. December 5, 2019
Houdini 18.0.310 Remove timestep scaling for velocity advection in the FLIP solver. It was accidentally left enabled when updating to the improved advection node. Thu. December 5, 2019
Houdini 18.0.310 HDA wrappers of Attribute Paint should correctly reset visualization when they enter the state and leave it. Thu. December 5, 2019
Houdini 18.0.310 Fixed bug with environment map orientation when using .exr files as maps. Thu. December 5, 2019
Houdini 18.0.310 Added an ordered menu to the Attribute Create TOP that can be used to control how the node should handle attribute type mismatches. Previously, the node would always error when attempting to create an attribute with the same name as an existing attribute and a different type. Thu. December 5, 2019
Houdini 18.0.310 Fixed an issue with the way work items copy the frame value from their parent work item. Previously the frame step was not copied, so all work items would have their step size reset back to 1 even if the parent work item had a different step value. Thu. December 5, 2019
Houdini 18.0.310 Fixed several issues with the SOP Import LOP when importing packed disk prims that reference .vdb files or .bgeo files containing VDB primitives. The Houdini geometry file format plugin now supports loading .vdb files, and unpacking USD packed prims that reference a USD Volume prim will now produce that volume's fields instead of empty geometry. Thu. December 5, 2019
Houdini 18.0.310 Fixed rainbow smoke visualization in the viewport. Thu. December 5, 2019
