19.5.800

Fixed timeout issues when running the PDG MQ server on a Deadline farm.

Wed. November 15, 2023
19.5.799

Fixed an issue where HDAs would recook when loading a sub level containing an HDA which references an actor in the same sub level.

Wed. November 15, 2023
19.5.799

Added support for the "Export Level Instance Content" input option to the old input system with packed level actors and level instances in world input.

This means that the "Export Level Instance Content" option is now functional in both the old input system and the new input system.

Tue. November 14, 2023
19.5.798

Fixed a regression in the PolyCut SOP from 19.5.634, where the Remove mode no longer removed edges where both points were exactly equal to the threshold value. When instead cutting edges, only edges which actually cross the threshold value are cut. The 'Points' mode and cutting by string attribute values were also fixed to match the updated logic for which edges are included.

Mon. November 13, 2023
19.5.798

Added support for enabling / disabling, and querying the enabled state, of the cook triggers (`On Parameter/Input Change`, `On Transform Change` and `On Asset Input Cook`) of a HoudiniAssetActor to the Public API.

Mon. November 13, 2023
19.5.795

Fixed a crash with sending array attribute data with `tupleSize > 1` to Houdini with HAPI.

Fri. November 10, 2023
19.5.795

Fixed a crash with visualizers when switching between LOPs and SOPs when a visualizer is active.

Fri. November 10, 2023
19.5.793

Fixed a regression with instancing in HoudiniGL when the instanced primitive had both a transform and an instance transform.

Wed. November 8, 2023
19.5.793

Fixed a bug with custom GLSL shaders that caused textures not to load if the custom shader only used the builtin glH textures.

Wed. November 8, 2023
19.5.793

Fixed a bug where cooking verbs in HOM would not work if the verb used OpenCL for the cook.

Wed. November 8, 2023
19.5.792
  • Fixed a crash that could occur when recooking a SkeletalMesh output.
  • Fixed an issue where a new output SkeletalMeshComponent was created foreach cook/recook of the same SkeletalMesh output, instead of reusing thepreviously created SkeletalMeshComponent.
Tue. November 7, 2023
19.5.792

Fixed a bug where custom collision meshes from a HoudiniAssetActor's temporary output would not be baked when baking the output of the HoudiniAssetActor.

Tue. November 7, 2023
19.5.791

Fixed a crash that can occur in some circumstances when diving into a Geometry object that contains SOP geometry with packed primitives.

Mon. November 6, 2023
19.5.791

Fixed a crash when viewing a LOP stage at the SOP level with a visualizer active.

Mon. November 6, 2023
19.5.791

Fix sporadic crash in Solaris when the viewport is set to XPU and displaying a node that requires multiple materials to be compiled.

Mon. November 6, 2023
19.5.791

Fixed a crash when adding multi/spare parameters while playing back with the Live Parameter Editor mode turned on.

Mon. November 6, 2023

Fri. November 3, 2023
19.5.788

The new input system now correctly identifies variations of input objects that are affected by the following input settings:

  • "Export Individual Paint Layers (Landscape)"
  • "Export Landscape Materials (Landscape)"
  • "Export Landscape Tile UVs (Landscape)"
  • "Export Landscape Normalized UVs (Landscape)"
  • "Export Landscape Lighting (Landscape)"
  • "Export Selected Landscape Components Only (Landscape)"
  • "Use Legacy Input Curves"
  • "Unreal Spline Resolution"
  • "Export Material Parameters"
Fri. November 3, 2023
19.5.788

Fixed a build error with UE5.0 due to a missing #include directive.

Fri. November 3, 2023
19.5.787
  • Made certain error messages more descriptive when creating input nodes.
  • Fixed an issue where the "Always Merge Input Geometry" wouldonly affect inputs connected to asset parameters and not asset inputs.
  • Added the ability to turn the input geometry into packed primativesbefore merging them together. This mirrors Unity's "Pack Geometry BeforeMerging" feature.
Thu. November 2, 2023
19.5.786
  • Fixed a bug where incorrect input nodes could be deleted when resendinginput data when using the new input system.
  • Fixed an issue where the landscape translator did not delete itsprevious input node when the landscape is re-exported using the new inputsystem.
Wed. November 1, 2023
19.5.786

Added the "Export Level Instance Content" world input option to the input UI / details panel. This option can be used to enable or disable exporting of Level Instance / Packed Level Actor content with world input when using the new input system. The option is enabled by default.

Wed. November 1, 2023
19.5.786

The plugin now exports Level Instance and Packed Level Actor content with world input in the new input system.

Wed. November 1, 2023
19.5.785

Add support for setting "Default" collision profile on static mesh components.
