Houdini Main Changelogs

Houdini 18.5.721 Fixed an issue where callback menu script didn't use the latest value when the menu button is clicked before the corresponding field has accepted a new value. Mon. October 4, 2021
Houdini 18.5.721 Fixed an issue where non-square heightfields were incorrectly converted to polygons by SOP Import. Mon. October 4, 2021
Houdini 18.5.718 Added the sidefx::maya_parm_callback_func and sidefx::maya_parm_callback_func_language built-in tags. These tags allow the user to define a callback that should be called when the associated parm is modified. Fri. October 1, 2021
Houdini 18.5.718 PDG now adds HOUDINI_PATH/pdg/types directory to the Python search path when loading custom node definitions, and restores the Python path back to what it was once it's done. This makes it easier to do relative imports between custom modules on the PDG search path. Fri. October 1, 2021
Houdini 18.5.718 The ROP Fetch TOP will now match at most one output per target ROP node, unless a list of output parm names was explicitly specified on the TOP node. Fri. October 1, 2021
Houdini 18.5.718 Version 2:
  • UE5: Fixed an issue where bake to actor would fail and not create any baked actors / assets
Fri. October 1, 2021
Houdini 18.5.718 Version 2:
  • Fixed loading of PDG output regression.
Fri. October 1, 2021
Houdini 18.5.716 Version 2:
  • Fixed an issue where input updates/changes via the public API, especially with curve inputs, would not always take effect.
  • Updated the public API documentation to mention that the API returns copies of the input configuration of an HDA and that to apply changes the SetInputAtIndex() or SetInputParameter() functions must be used.

Houdini 18.5.717 The TOP Network parameter from the TOP Network Cook Controls property can now be set to a specific TOP node. This makes it possible to promote the work item dot display of a specific node in a TOP Network to a different node. Previously, it was only possible to promote the dot display for the entire network itself. Thu. September 30, 2021
Houdini 18.5.716 Version 2:
  • Initial support for generation of landscapes with edit layers (using Generate output mode).
  • Fixed various issues with Modify landscape output mode.
