Mon. December 2, 2024
20.0.895

Added support for landscape creation in Unreal 5.5.

Wed. November 20, 2024
20.0.895
  • 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.
Tue. November 19, 2024

  • Fixed crash with landscape spline inputs.
  • Fixed incorrect LandscapeSpline input Rotation values.
  • Fixed incorrect LandscapeSpline input Mesh scale values.
  • Prevent an unreal crash if failing to commit landscape splines.
Tue. November 5, 2024
20.5.395
  • Added support for Starting/Stopping HAPI Performance monitoring.This can be done by using the Houdini.StartHAPIPerformanceMonitorand Houdini.StopHAPIPerformanceMonitor commands respectively.The performance logs can then be easily viewed when using session syncby opening the Performance Monitor in Houdini.The HAPI traces are stored in the current unreal trace directory.
  • Added support for the "unreal_pdg_asset" detail attribute.It can be used to indicate to the plugin if an HDA is expected to use PDG.This is especially useful on big HDAs that contain a lot of nodes - as itwill speed up instantiation and rebuild times significantly.
  • Added other optimizations for large HDAs.
  • Rebuilding an HDA no longer causes every parameter to be individuallyre-set on the Houdini side.
  • The plugin now relies on parameter presets for setting parameter onrebuilt/loaded HDAs. This significantly reduces the time needed for theseoperations on big HDAs that have a lot of nodes and parameters.
