Mon. October 28, 2024
20.5.399

Fixed a bug in the RBD Bullet and RBD Configure SOPs which prevented glue pin constraints from working as expected, potentially leading to some jittering on the first frame of the sim.

Add support for string::Format and Log for basic array types.

Sat. October 26, 2024

20.5.398

Improved handling of engine licensing when calling python callbacks in husk in several ways. For example, specifying "--allowed-procedurals all" will only check out an engine license if the procedural actually requires one.

Thu. October 24, 2024

Improvements made to sesinetd auto install feature.

Wed. October 23, 2024

Fixed a bug with the helps launch feature trying to launch with the wrong file.

Wed. October 23, 2024
20.5.396

Deleted the FillData function from the generic HAPI C# bindings, specifically HECSharp_StructMembers.cs because it is specific to HE for Unity's implementation of curves.

Wed. October 23, 2024
20.5.396

Fixed a possible crash in IPR when the AOV specified by Variance Pixel Oracle's "Plane" parameter no longer exists upon render restart.

Wed. October 23, 2024
20.5.396

Fixed a bug on the reverse foot where the controls can flip when using negative scales on the joints.

Wed. October 23, 2024
20.5.395

XPU: Fixed a crash when a material update in a scene with nested instances caused Optix device to crash.

Wed. October 23, 2024
20.5.396

setParmsFromData errors because of wrong function args in nested function -Fix a bug, where this function would error when running because of missing

required arguments.
Wed. October 23, 2024
20.5.396

When husk was rendering only non-raster products (i.e. rendering only a deep image with no beauty image), only the first AOV from the non-raster render product was created. This meant that the AOVs might not be available to the render delegate for the non-raster product. Now, husk will create all the AOVs when it creates the dummy raster product.

Wed. October 23, 2024
20.5.395

Added parameters to the Python Processor that allow it to filter and ignore upstream failed dependencies. These options were already available via the pdg.NodeOptions configuration object in Python, but previously weren't promoted up to parameters on the Python Processor itself.

Tue. October 22, 2024
20.5.394

XPU: added new envvar "KARMA_XPU_DEVICES" which allows to enable/disable multiple devices via a single envvar entry (see envvar docs for details). (please note this superceeds the previous KARMA_XPU_DISABLE_DEVICE_n style, but does not replace KARMA_XPU_DISABLE_OPTIX_DEVICE or KARMA_XPU_DISABLE_EMBREE_DEVICE given they have their own benefit of initializing the device type to start with)

Tue. October 22, 2024
20.5.395

Added support for the status operation to the Perforce TOP.

Tue. October 22, 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.
