Thu. October 24, 2019
Houdini 17.5.418 Fixed a bug where calling the `hou.ui.selectFile()` HOM function with the `file_type` argument set to `hou.fileType.Hip` opened a file chooser that failed to list *.hipnc and *.hiplc files. Wed. October 23, 2019
Houdini 17.5.417 Unity plugin:
  • Added support for uploading quad topology input meshes without converting to triangles.
  • Added optional destination path to export prefab to in HEU_HoudiniAsset.BakeToNewPrefab.
Tue. October 22, 2019
Houdini 17.5.417 Fix for extraneous dependencies being added in the Network View pane. In general, the issue was because a dependency gets added any time an expression is evaluated, and in the case when no nodes are cooking, added to the current network cwd. Tue. October 22, 2019
Houdini 17.5.417 Fixed bug where changing the Apply Zoom to Background display option did not redraw the viewport. Tue. October 22, 2019
Houdini 17.5.416 Unity plugin:
  • Fixed baked terrain not getting layers.
  • Added support for specifying a string parameter to be treated as an asset path parameter in Unity, by adding tag named "heuassetpath" to parameter. This allows to drag & drop assets or choose from asset library in Unity.
  • Now copying overridden collider mesh on instance over to the baked instance.
  • Now returning the newly created prefab or gameobject when baking.
Mon. October 21, 2019
Houdini 17.5.416 Fixed a bug in the Alembic ROP that resulted in Alembic layers that override transform values when not instructed to do so. Mon. October 21, 2019
Houdini 17.5.415 Fixed a bug in the ixres and iyres COP VEX functions. Sun. October 20, 2019
Houdini 17.5.413 Fixed a crash in the Pyro and Smoke solvers when running in OpenCL mode on the CPU on OSX. Fri. October 18, 2019
Houdini 17.5.413 Unity plugin: Added support for disabling TerrainCollider in the plugin source via the HEU_TERRAIN_COLLIDER_DISABLED script define. Fri. October 18, 2019
Houdini 17.5.413 Fixed a bug where the Attribute from Map SOP wasn't handling non-default UV Attribute names correctly. Fri. October 18, 2019
Houdini 17.5.413 Fixed a bug where the Attribute from Map SOP wasn't handling non-default UV Attribute names correctly. Fri. October 18, 2019
Houdini 17.5.413 Fixed HAPI_GetWorkitems and HAPI_QueryNodeOutputConnectedNodes. Fri. October 18, 2019
Houdini 17.5.413 Unity plugin: Added support for overriding the collider mesh for instances when using unity_instance attribute on point clouds. To do so, another string attribute called "collision_geo" that points to the collider asset path needs to be specified. Then the collider assset's mesh will replace the created instances' collider mesh. Fri. October 18, 2019
Houdini 17.5.412 Fixed a bug in the Vellum Solver's String constraints that could lead to NANs and stalled simulations, usually when in use with the OpenCL CPU driver. Thu. October 17, 2019
Houdini 17.5.412 Duplicate shape bindings are now ignored when loading or creating a layer. This scenario previously could result in a variety of display issues in the viewport. Thu. October 17, 2019
Houdini 17.5.411 Fix some cases where the optransform() and originoffset() would evaluate always evaluate as being time dependent. Wed. October 16, 2019
Houdini 17.5.411 The Vellum Solver will now use the identity rotation of {0, 0, 0, 1} for any orientation pins with Match Animation enabled, when the target geometry does not actually have an orient attribute. Previously in that situation the solver would use {0, 0, 0, 0}, which could lead to NANs with the OpenCL CPU driver. Tue. October 15, 2019
Houdini 17.5.410 Fixed a bug in the Vellum Constraints SOP that could compute the wrong orientation for a Soft orientation pin on the last vertex of a hair, if the previous vertex was not also in the specified point group. Tue. October 15, 2019
Houdini 17.5.406 Fixed a few bugs where the "Follow selection mask" display option wasn't always properly respected when initially diving into an object.

Fixed a bug where area selecting in a component selector at the object level did not detect a selection and so did not dive into the object.
