Houdini Main Changelogs

Houdini 18.0.481 ImageMagick node: added support for a PDG_IMAGEMAGICK_DIR environment variable on Unix platforms for installations of ImageMagick which have separate executables for the various commands (convert, montage, etc). 昨日
Houdini 18.0.481 Fixed an issue that was causing the pdg.WorkItem.makeActive context manager to not work correctly unless it was used in a script that was already part of PDG graph evaluation. 昨日
Houdini 18.0.481 Added "Bake Dummy Object" option that controls whether the dummy object is also baked out when baking geometry HDAs. When this option is disabled, nodes of baked geometry will be top-level nodes in the scene. 昨日
Houdini 18.0.481 Fixed an issue with the ROP Geometry TOP node not correctly dirtying itself on a subsquent graph cook, after making a change to the embedded SOP network inside that TOP. 昨日
Houdini 18.0.481 Fixed a harmless assertion in PolyReduce 2. 昨日
Houdini 18.0.481 Added additional debug logging when the plugin is unable to start the out of process session (HARS.exe). 昨日
Houdini 18.0.481 Fixed hotkey warning for Houdini Engine SessionSync. 昨日
Houdini 18.0.481 The Cache LOP now properly clears its cache in Cache Cooked Frames mode when the input node changes. 昨日
Houdini 18.0.481 Added the Path Deform SOP which deforms an object along a spine curve. 昨日
Houdini 18.0.481 The HAPI cook thread is now shutdown in HAPI_Cleanup, as well as when the application exits. 昨日
Houdini 18.0.480 Fixed a potential bug when exiting houdini with python script work item still running. 水. 5月 27, 2020
Houdini 18.0.480 Unity plugin: Enabled new SessionSync which is accessible via HoudiniEngine menu in Unity. Improved the session management through SessionSync panel. Removed the Connect to Debugger menu options. Updated online documentation with SessionSync section. 水. 5月 27, 2020
Houdini 18.0.480 Fixed some cases where extra viewport geometry processing was happening when changing the viewport layout. 水. 5月 27, 2020
Houdini 18.0.480 The Geometry Import TOP node now supports adhoc groups when specifying a group to import as a work item. 水. 5月 27, 2020
Houdini 18.0.480 Fixed a buffer overrun in Copy To Points 2.0 SOP when copying single vertex primitives by id. 水. 5月 27, 2020
Houdini 18.0.480 * Moved the Options and Debug tabs into an Options dialog found in the

    Houdini Engine menu.

* The plugin will now save any Houdini session configuration to the user's

preferences, which means that these settings will now be preserved across 3ds Max sessions.

Houdini 18.0.480 Fixed an issue where multiparms could fail to initialize. 水. 5月 27, 2020
Houdini 18.0.480 The Transform Pieces SOP no longer promotes a primitive 'name' attribute to a point attribute on the output geometry. 水. 5月 27, 2020
Houdini 18.0.480 Fixed issues where the Transform Pieces SOP would promote a primitive 'name' attribute on the input to a point attribute on the output geometry. The input attributes are now correctly preserved, and temporary attributes are used internally instead. 水. 5月 27, 2020
Houdini 18.0.480 Fixed the USD preview shader translation for Material Builder VOPs. 水. 5月 27, 2020
Houdini 18.0.479 This fix prevents the selector toolbox to be displayed by default in the viewport toolbar when a SOP state is activated. This allows SOP python states, for instance, to display only their parm states if the selection toolbar is not required. 火. 5月 26, 2020
Houdini 18.0.479 The old Stroke State and the locating of the old Brush states will use the standard tolerance of 5e3f rather than 0.1f. This means they will be a lot faster on small geometry. (very small geometry will stil start to run into issues, but at the same scale that the other operations already fail at) 火. 5月 26, 2020
Houdini 18.0.479 Clear errors on HDA ROPs each time a render is started. 火. 5月 26, 2020
Houdini 18.0.479 New SessionSync feature added:
  • Replaces the old Houdini Engine Debugger. New panel can be opened from Windows menu or New Pane Tab Type > Misc.
  • Can now automatically start SessionSync when launching Houdini via command argument -hess. Allows to specify pipe session (e.g. -hess=pipe:<name>) or socket session (e.g. -hess=port:<index>).
  • Added 'Cook using Houdini Time' option which allows HAPI to cook using Houdini's time line.
  • Does auto layout of new nodes created from client side.
  • General improvements for running Houdini Engine inside Houdini through SessionSync.
  • Updated help documentation.
火. 5月 26, 2020
Houdini 18.0.479 Added new APIs:
  • HAPI_GetTotalCookCount to get total cook count of a node and its children. This allows to poll from client side to see if node needs to be recooked in HAPI and its geometry regenerated.
  • HAPI_SetSessionSync to enable internal SessionSync mode in Houdini Engine in order to achieve SessionSync behaviour. This is automatically set when starting from inside Houdini.
  • HAPI_GetUseHoudiniTime and HAPI_SetUseHoudiniTime to set whether Houdini Engine should use current Houdini time for cooking.
  • Added HAPI_SaveNodeToFile and HAPI_LoadNodeFromFile to save and load node networks in current Houdini Engine session. Note that this is experimental for now.

Bumped HAPI version
