Houdini Main Changelogs

Houdini 18.5.556 Subnetwork inputs and operator path parameters can now be cleared via the MaxScript API by passing the undefined value instead of an INode to the SetGeometryHdaInput, SetModifierHdaInput, SetGeometryHdaOpParmInput, and SetModifierHdaOpParmInput methods. yesterday
Houdini 18.5.556 Fix LOD ranges for input values between 0 to 100. yesterday
Houdini 18.5.556 Fixed an issue with the "Block on Failed Work Items" toggle not working properly with the Tractor Scheduler. Retrying a failed task from the Tractor farm interface when that option is enabled will now correctly schedule downstream work items that were waiting on the failed task. yesterday
Houdini 18.5.556 Fixed an issue where previously saved curves would not duplicate correctly. yesterday
Houdini 18.5.556 Animation curves, colors, and gradients auto cook only when your mouse is released to prevent autocooking with interfering with UX. yesterday
Houdini 18.5.556 Textures will respect .tga and .exr extensions instead of converting them to .png yesterday
Houdini 18.5.555 Version 2:
  • Textures from Houdini Materials are now created only if the corresponding "use" parameter isn't disabled.
  • Reduced the number of HAPI calls when translating Houdini materials.
  • Optimized mesh creation.
(removed redundant calls to Physics/NavCollisions functions that are already part of the StaticMesh::Build function)
  • Mesh creation: removed unecessary attempt to load an unreal material with an invalid path.

Houdini 18.5.555 Added new method (DeleteHda) to the MaxScript API which can be used to cleanly delete geometry HDAs and modifier HDAs. Wed. April 21, 2021
Houdini 18.5.555 Fixed crash that could occur when deleting a geometry HDA after deleting some or all of its child geometry nodes. Wed. April 21, 2021
Houdini 18.5.555 Fixed an issue with the Validate Output Files toggle not invoking custom cache handlers when validating outputs. Wed. April 21, 2021
Houdini 18.5.555 Fixed build errors caused by making a HAPI call at runtime. Wed. April 21, 2021
Houdini 18.5.555 Added support for auto generated HDRP/URP materials.
  • HDRP/URP materials will use a simple vertex color shader, similar to the previous HoudiniVertexColor shader
  • Note that if you have a HDRP project, you may get a non-fatal error regarding the deserialization of URP shaders, and vice versa. This error can be ignored, or you can just not import the shadergraphs of the render pipeline that you are not using.
  • Additionally added support for auto-generated terrain materials in HDRP/URP
Wed. April 21, 2021
Houdini 18.5.555 Fixed a bug where the Character Blend Shapes SOP behaved incorrectly if a shape's points or primitives were not contiguous in the shape geometry. Wed. April 21, 2021
Houdini 18.5.555 Fixed issue where nodeSync on a Experimental/Object/Geometry node has broken UI and does not update along with session sync. Wed. April 21, 2021
Houdini 18.5.555 A few improvements to the Reverse Foot SOP:
  • Added an option (when Mode is set to Solve) for whether the markers' transformation delta is applied. Disabling this can be useful to avoid a double transform when both the markers and foot joints are being transformed before the solve.
  • Fixed an issue where the up axis marker offset was applied incorrectly.
  • Mirroring entries using the Mirror Entries button now also mirrors the marker scale value.
Wed. April 21, 2021
Houdini 18.5.555 Fixed a bug which could cause AgentClip-2.0 to get localtransforms with incorrect scale and translation components when using a MotionClip that had a scaleinheritance other than 0. Wed. April 21, 2021
Houdini 18.5.554 Fixed issue where baked curve geometry would remain parented to the HDA container node. Tue. April 20, 2021
Houdini 18.5.554 Added an option to add a primitive attribute to imported geometry that stores the path to the GLTF node that contains the primitive. Tue. April 20, 2021
Houdini 18.5.554 Fixed a bug with the Switch TOP cooking all input TOP nodes, and therefore erroring out if there was an invalid node configuration in one of the non- active input branches. The node will now only cook the selected input, as defined by the switch index parameter. Tue. April 20, 2021
Houdini 18.5.554 Fixed a bug with dependency lines not appearing for batch work items inside subnets, when the subnet contains multiple nodes with batches. Tue. April 20, 2021
Houdini 18.5.554 parameters now have tooltips with their name by default Tue. April 20, 2021
Houdini 18.5.553 Update the Vellum Solver to work properly with NVIDIA's recently released OpenCL 3.0 drivers, particularly the Pressure and Shape Match constraints. Mon. April 19, 2021
Houdini 18.5.553 Added a new Cache Mode parameter entry that causes the node to only check output files for work items in that node, and ignore any cache invalidation caused by upstream work item changes. The new options is available on all processor nodes that have the Cache Mode parameter. Mon. April 19, 2021
Houdini 18.5.553 Fixed a bug that could cause slow viewport performance for agents in certain scenarios. Mon. April 19, 2021
Houdini 18.5.553 Fixing several issues with the peak usage logging.
  • Fixed an issue with the start/end date options
  • Fixed the --no-progress-info option
  • Fixed an issue with the progress line not being cleared.
  • Use the timezone found in the log if one is not provided.
