Husk now handles the "dummy raster product" filename better with the -o command line option. In some cases, the delegate and husk would write the same output file when -o was specified. This should no longer happen.

Added support for landscape creation in Unreal 5.5.

Performance improvements for landscape creation.

• Added support for the "unreal_pdg_asset" detail attributes.This can be used to indicate to the plugin if the HDA is expected (or not)to use PDG. This is especially useful on big HDAs that contain a lot of nodesas it will speed up instantiation and rebuild times significantly.
• Improved the logic used when parsing TOP Networks and when automaticallyidentifying PDG Assets.
• Improved performance when instantiating/processing large HDAs.
• Rebuilding an HDA no longer causes every parameter to be individually re-seton the Houdini side. This significantly reduces the time needed for theseoperations on big HDAs that have a lot of nodes and parameters.
• Fixed errors/warnings for UE5.5.

The "non-bypassed" node flag is now properly considered as recursive by HAPI_ComposeChildList. Bumped HAPI version to 6.2.4.

Fixed viewer update of object transforms when navigating in and out of subnet objects in Hide Other Objects mode.

Fix a bug with the Feather Procedural where barbs weren't deformed with the animated surfaces in some configurations.

Fixed an error when readin the ouput name from a primitive or detail attribute.

Fixed landscape creation in Unreal 5.5

Fix degenerate cases when computing bezier() segment slopes on animation channels.

Update the Curve state so that clicking on an intermediate point of an existing curve in draw mode with no active curve will now begin drawing the new curve from a branch point.

Fixed an issue in the Bullet solver which could cause minor changes to simulation results when resimulating from an older cached frame after a parameter change.

Fixed a bug that was causing HAPI_GetPresetNames to crash when using Thrift sessions.

Fixed Blendshape component skel input and output connection, it will now be connected to the point transform and the output, to propperly set the detail attribs on the skeleton.

Fixed a bug in the Bullet solver which caused animated static objects to not be interpolated correctly when resimulating the last frame (e.g. after a parameter change).

Fixed the returned order of nodes and ports when running a search of an APEX graph. The prior order was a depth first search which would iterate through the nodes of the subnets in revert point order. The new default order is a depth first search which iterates through the nodes of the subnet in forward point order. Additional options have been added to search in a breadth first search order. This change alters the results of the following APEX callbacks:

• graph::FindNodes
• graph::FindFirstNode
• graph::FindPorts
• graph::FindFirstPort

It also alters the results of the following APEX python functions:

• apex.Graph.matchNodes(...)
• apex.Graph.matchFirstNode(...)
• apex.Graph.matchPorts(...)

Fixed missing Baseskeleton port on the Blendshape component.

Fixed inefficient labeling data structure in unsubdivide SOP.

Updated nodes that where affected by the new sort order change in the updated findNodes callback.

Fixed a bug where some animation could be lost when merging APEX Animation Layers in certain cases.

The new --gpu option for husk will allow husk to use delegates which require OpenGL, Vulkan or Metal. This lets husk render using HdStormRendererPlugin for example.

Fixed an issue with `handler.removeFromAllEmitters()` hanging when called from within an Python event handler function.

Fixed a performance regression with string hashing vs 20.0 which could affect many parts of Houdini, such as merging geometry with string attributes.
