• 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 unreal_output_name not being read correctly for primitive and detail attributes.

Fixed crash in the Flipbook ROP when the output resolution is changed.

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

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

Fix that can happen when switching to Rig Tree pane under particular circumstances.

Added support for landscape creation in Unreal 5.5.

Fixed an isse where the edit layer name could be ignored when creating a landscape.

Landscape import performance optimizations.

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

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

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

Added new callbacks to APEX's string library: ToInteger, and ToFloat.

Added 'A' (albedo) event type in light path expression so that it's possible to write out albedo AOV based on specific path or BSDF component.

Fixed a bug where box-select wouldn't select instanced primitives on macOS

Fixed Edit Material Network LOP which would occasionally use Generic VOP instead of the Mtlx Standard Surface VOP.

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

Hide deactivated lights from the light linker since it has no way to activate them.

Fix CH_Manager.h in the HDK to work around a bug in gcc13 so this compiler can be used to build HDK plugins that include this header.

Fix update issue when locking/unlocking a parameter in the light mixer.

Fix hotkey editor showing the Esc key assignment window when pressing enter in the search field.

Fixed a potential crash in the APEX Character Deformation display option, along with a bug that could cause stuck geometry in certain situations.

Update Houdini's USD library to include the following fix:

• Avoid crash when writing USD to volumes mounted to NTFS folders

Fixed a crash when using detail-level material assignment on particles
