Houdini Main Changelogs

Houdini 16.5.393 Fixed a bug where Houdini would crash when running a node parameter callback script that removed nodes from the scene. yesterday
Houdini 16.5.393 Added an option to the terrain projection foot sampling mode to control whether the foot positions are projected onto the agent's plane before sending the rays. This can avoid lowering the agent too far if, for example, none of its feet are planted in its current pose. yesterday
Houdini 16.5.393 FlipbookSettings.visibleTypes() now properly updates the visible types. yesterday
Houdini 16.5.393 Fixed bug causing sockets to sometimes be duplicated upon recook. yesterday
Houdini 16.5.393 Fixed a viewport crash when closing a Scene View which was set to the UV Viewport. yesterday
Houdini 16.5.392 Group information are now available on Packed primitives. Instanced packed primitives will now generate Hierarchical Instanced Static Meshes if the packed primitive has LOD groups. Collisions groups are now handled properly by packed primitives. Fixed crash due to invalid LOD groups. Better support of ComponentTags via generic attributes (unreal_uproperty_ComponentTags). Tue. February 20, 2018
Houdini 16.5.392 HAPI: Added functions for accessing group information on packed primitives:
  • HAPI_GetGroupCountOnPackedInstancePart for getting the number of groups in a packed prim part.
  • HAPI_GetGroupNamesOnPackedInstancePart to get the names of the various group in a packed prim part.
  • HAPI_GetGroupMembershipOnPackedInstancePart to get the membership for a given group in a packed prim part.
Updated HAPI version to 3.2.9
Tue. February 20, 2018
Houdini 16.5.392 Fixed an viewport alembic regression that caused changes to be ignored in some cases. Also fixed a bug with Alembic instancing that created far more instances than intended. Tue. February 20, 2018
Houdini 16.5.391 Fixed the Save -> Edit Data Channels dialog that wouldn't reopen after its first opening. Mon. February 19, 2018
Houdini 16.5.388 Fixed the hou.Geometry.addArrayAttrib() HOM method so that it recognizes the `tuple_size` keyword argument. Fri. February 16, 2018
Houdini 16.5.388 Fixed a bug with object-level viewport instancing that could appear if some of the points instanced upon were deleted in the SOP network. Fri. February 16, 2018
Houdini 16.5.387 Tweaked the zoom speed when approaching the viewport pivot. Also handle tall & thin viewports better when zooming. Thu. February 15, 2018
Houdini 16.5.387 Greatly reduced mantra's memory footprint when rendering packed primitives that use a large detail attribute style sheet on the container geometry to express the material assignments on the instances. Thu. February 15, 2018
Houdini 16.5.387 Fixed transform animation of deforming Alembic primitives. The transform was being treated as constant. Thu. February 15, 2018
Houdini 16.5.387 Fixed an error when running the Bake Agent shelf tool multiple times, and the first clip did not set up foot planting channels but a later clip did. Thu. February 15, 2018
Houdini 16.5.387 Fixed potential crash with DCM when rendering volumes with stochastic transparency. This bug was introduced in 16.5.366. Thu. February 15, 2018
Houdini 16.5.387 On macOS, Houdini by default now selects the discrete GPU over the integrated one for OpenCL operations. This applies only to mixed GPU, Mac systems. Thu. February 15, 2018
Houdini 16.5.386 Fixed an Alembic regression in yesterday's Alembic fixes which resulted in a threading issue, which could manifest as update issues and crashes. Wed. February 14, 2018
Houdini 16.5.386 Fixed warnings about unexpected parameters in the Prepare Render Jobs HQueue job. Wed. February 14, 2018
Houdini 16.5.385 Color on alembic primitives now updates more reliably in the viewport when only the color changes. Tue. February 13, 2018
Houdini 16.5.385 Fixed a bug where PyQt/PySide QCheckBox objects were invisible on some platforms when styled by the Houdini Qt style sheet. Tue. February 13, 2018
Houdini 16.5.385 Fixed a bug where object-level "Shutter Offset" parameter was being ignored by volume primitives when using velocity blur. Tue. February 13, 2018
Houdini 16.5.385 Fixed a threading bug with viewport alembics which could cause the order to change between updates, resulting in corrupt meshes (black, missing, incomplete). Tue. February 13, 2018
Houdini 16.5.385 The gply utility now exports integer attributes as integer properties, and loads integer properties as integer attributes whenever possible. Tue. February 13, 2018
Houdini 16.5.385 Added support for short, ushort, int16 and uint16 data specifiers to gply, and fixed a bug where it would miss an invalid vertex index. Tue. February 13, 2018
