Some hydra delegates were expecting the data returned by GetRenderStats() to automatically make it through to the renderered image's metadata. This was the behaviour in H19.5 and earlier. There's now a new setting in UsdRenderers.json which specifies with data from the render stats should be translated verbatim to image metadata. This default to "*" so that if a delegate hasn't set up metadata translation, all of the render stats will be saved as metadata.

When the "Attributes" toggle on the Agent Definition Cache SOP is enabled, the agent's current clip name is included in the cache. This is used to restore the original clip by default if the Clip Name parameter is not specified.

Fixed an issue where level instance data would not be correctly imported into Houdini.

Fixed an issue where landscapes would be imported into Houdini with different sizes on different layers.

Fixed an issue with level instances not baking in non-world partition levels.

Fixed an issue level instance inputs would not always be uploaded to Houdini.

Fixed an issue with the RBD Car Follow Path SOP where wheels would keep moving when the vehicle was stopped and springs were enabled. Fixed an issue where the animated steering would jitter when the vehicle wheels might be positioned ahead of the next frames depending on terrain geography. Added support for reversing the vehicle along the curve. Improved dynamic reversing.

The File::New Asset Python options for Compositing are suffixed - Old as they refer to the old Compositor. The Subnet option for Compositing is likewise taged old, and a new Copernicus option added.

Added support for geometry inputs and outputs in compiled blocks.

Fixed an issue where animation matrices would be scaled in Houdini when importing from Unreal.

Internal unit test updates.

Fixed an issue where masks on height fields could sometimes have the wrong size when exporting to Houdini from Unreal.

Added support for exporting Physics Assets for Skeletal Meshes from Houdini to Unreal. An auto-generated Physics Asset is now created by default.

Added internal tests for Unreal presets.

Python States - Delay node change event setup

• Fix a bug in the python states support that could potentially lead to anexception if node events are sent during an `onEnter` callback.

Packages - browser package editing bug

• Fix a bug in the browser to avoid reloading a deactivated package after editing.

Fixed an issue where level instances would not always bake in non-world partition levels.

Fixed missing parameter descriptions in the help tool tips of the ROP GLTF Output SOP node.

Improve performance for pick id render passes with large number of primitives

Change element index layout for meshes with no vertex attributes giving some performance improvement for some scenes

• Fix Bug where face selection would not handle the front only or back only option
• Fix transparent objects not recieving shadows
• Fix Bug where wrong instances would be highlighted when doing point selectionon an instanced primitive

Fix a viewport crash in some high VRAM usage scenarios

Added new %payload primitive pattern auto collection which matches any prim with a payload composition arc.

When collapsing nodes to a subnet in COPs, the output type will be set from the input type of the output node, rather than the output type.

Fixed a performance regression with packed prims in both Vulkan and GL renderers.
