Houdini Main Changelogs

Houdini 15.5.710 Fixed possible incorrect display when removepoint() VEX function deletes a point that is used by a primitive, in an Attribute Wrangle SOP or Attribute VOP SOP. Thu. January 5, 2017
Houdini 15.5.709 If the Agent Prep SOP's Create Foot Plant CHOP Network option is invoked multiple times, it will now update the existing CHOP network to add any missing clips instead of building a new network. Wed. January 4, 2017
Houdini 15.5.709 The Simulate shelf tool now prompts the user for what action should be taken when the selected agents are already simulated. A new simulation can be created, or new states can be added into the existing simulation. Wed. January 4, 2017
Houdini 15.5.708 Fixed a potential crash when unpacking agents that have deforming shapes. Tue. January 3, 2017
Houdini 15.5.708 Fixes for layering nested pxrlayermixer nodes and layering refraction. With this change, pxrlayermixer and pxrlayer nodes will need to be recreated. Tue. January 3, 2017
Houdini 15.5.696 Fixed a bug where the HQueue server installation failed on Windows when the server was installed into a path that contained whitespace. Also fixed similar bugs in the HQueue Server and Client services. Thu. December 22, 2016
Houdini 15.5.695 Attribute Copy SOP will no longer crash if attribute matching generates an empty string during auto-detect. Wed. December 21, 2016
Houdini 15.5.694 Generated mesh sockets can now have pre-assigned Actors (via the "unreal_mesh_socket_actor" string attribute)

Actors can now also be assigned to an asset's sockets by using "Attach To" in the context menu or by drag and dropping the actor on the asset in the world outliner panel.

Added the option to "Open in Houdini" when right-clicking on an asset in the content browser.

Tue. December 20, 2016
Houdini 15.5.692 Fixed a crash in the Performance Monitor that occurred when deleting a profile and then attempting to stop recording it afterward. Sun. December 18, 2016
Houdini 15.5.692 Fixed a HOM bug where running hou.Node.createDigitalAsset from the Python Shell crashed Houdini. Sun. December 18, 2016
Houdini 15.5.692 Fixed a HOM bug where hou.Node.parmsInFolder() failed for simple, collapsible and radio folder types. Sun. December 18, 2016
Houdini 15.5.689 Baking now updates the output of the last bake instead of creating new files each time. Renaming or moving such files will prevent them from being modified. Thu. December 15, 2016
Houdini 15.5.689 Added the option to "Rebuild All Instances" of an asset in the content browser context menu. It will reimport and rebuild all instances in the scene of the selected assets. Thu. December 15, 2016
Houdini 15.5.689 Fixed HOM to allow *AsString functions (like hou.Geometry.pointFloatAttribValuesAsString) to return binary representation that is larger than 2GB. Thu. December 15, 2016
Houdini 15.5.688 Added support for mesh sockets:

These can be created by adding points to a group starting with the "socket" prefix.

The sockets rotation and scale can then be defined using "rot" and "scale" attributes. The rotation can also be deduced from the normal ("N") attribute if the socket points do not have rotations attributes.

Their name can be defined using the "unreal_mesh_socket_name" attribute.

Wed. December 14, 2016
Houdini 15.5.688 The Alembic Xform Object now has a parameter to fetch an object's world transform instead of its local transform. Wed. December 14, 2016
Houdini 15.5.688 Fix crash when using a bone path in the Capture SOPs for the extra regions and then using a path to a CaptureRegion SOP. Wed. December 14, 2016
Houdini 15.5.688 Optimized the Alembic SOP when loading geometry as bounding boxes. Wed. December 14, 2016
Houdini 15.5.688 Added support for baking instanced overrides to a Blueprint. Handles audio, particle systems, Blueprint actors and native actors. Wed. December 14, 2016
Houdini 15.5.688 Fix for unlocked asset inside the SBD Constraint. Wed. December 14, 2016
Houdini 15.5.688 Fix bug where hicon: paths in the Type Properties dialog would not generate an embedded IconSVG section in the HDA. Wed. December 14, 2016
Houdini 15.5.688 Fixed an issue in the crowd solver where the Max Turn Rate control affected changes in orientation from the locomotion channel, instead of just changes caused by e.g. external forces. Wed. December 14, 2016
Houdini 15.5.686 Added support for UE's "Simplified" collisions:

In the same way that the UCX colliders are handled, simplified collision mesh can now be baked in a static mesh's body setup instead of using a separate mesh component.

This can be achieved by using the rendered_collision_geo_simple and collision_geo_simple groups.

The type of the desired collider can then be appended to the group name to specify its type: box, capsule, sphere, kdop10X, kdop10Y, kdop10Z, kdop18 or kdop26

Mon. December 12, 2016
Houdini 15.5.683 Added support for UCX collisions in the Unreal plug-in.

Collision meshes can now be cooked in a static mesh's BodySetup as convex hulls instead of requiring a separate mesh component. This is the recommended workflow and is used by the FBX importer as UCX/UBX.

This can be achieved by using the rendered_collision_geo_ucx or collision_geo_ucx groups.

Boxes and spheres primitives are also treated as ConvexElements as this the recommended behavior by UE.

Fri. December 9, 2016
Houdini 15.5.683 Channel names for deep images are no longer sanitized. This makes deep image channels behave the same way as flat images (see the journal entry for Aug 10, 2016 - Houdini version 15.5.565). Fri. December 9, 2016
