These release notes describe changes from Katana 6.0v3 to 6.5v1.
For a high-level overview of important changes in the Katana 6.5 line, please see the accompanying What's New in Katana 6.5 document.
Added support for OpenVDB Volumes in Hydra, UsdVol importing via UsdIn and UsdToKatana, and new Volume attribute conventions which can be found in the developer-guide AttributeConventions/OtherTypes.
The Attributes tab now shows USD property values!
Any selected USD location made in the Scene Explorer tab will show its property values in Katana's existing Attributes tab.
As part of this feature, the Attributes tab has been repurposed to show the appropriate information for any selected USD location. Therefore the following will now be supported in the Attributes tab:
Introducing expansion-based loading in addition to further controls for loading USD locations in the USD working sets! By default all USD working sets, except Live Rendering, will be disabled. While in this mode, users will be able to view USD location data through deferred recursive expansion of their scene tree. However, this will be disabled when the following working sets are enabled.
USD Viewer Visibility Working Set: When enabled, USD location visibility to the Hydra viewer will be driven by this working set. The states in which each location is viewed will act in the same manner as on the Katana side. Therefore locations can be either included with or without inheritance, or excluded with or without inheritance, matching the same workflow as the Viewer Visibility Working Set seen in the Scene Graph tab. Important to note, if a child location is explicitly included then ancestors will also be visible regardless of their current state.
Payload Working Set: When enabling the Payload Working Set, users can control the loading of each payloads in accordance with USD’s definition of Payload rules; and these will be visualised in the following manner:
To determine if a USD has a payload, and whether that payload is either loaded or unloaded, will be represented in the working set icon as an arrow.
The background color behind the payload arrow indicates which Payload rule is set at each location. These rules are in accordance to the USD definition of Payload rules and are visualised in the working set icon as follows:
Active Prim Working Set: When this working set is enabled, a user can control whether a USD prim is included or excluded from their stage using this working set. The workflow to represent how a prim is loaded and included in your USD stage will be the same as the Payload Working Set. Therefore, to determine whether a USD prim is either active or inactive will be presented by the power icon. When the power icon is:
Whereas the background color represents the various states, therefore:
UI Improvements
Defaulted Native USD Nodes can be distinguishable from Katana nodes with a light-blue background and a blue stripe down the left hand side of the node when placed in the Node Graph tab to improve the readability. Further customization to the background of these nodes can be done in the Colors menu in the Node Graph tab.
Merge node changes
The Merge node has now been refactored to support USD native nodes and Geolib nodes. Users can specify the input priority order for each in the Parameters tab.
Native USD Nodes are now available in Katana
More details on the above nodes can be found in their help dialogs.
Incorporation of a Native USD Framework for more customization
Support for utilising custom USD for the USD Native workflow in Katana has been implemented in this release. The source for FnUsdAbstraction, and a readme detailing how to build and use your own custom USD (via the abstraction library) is found within the Katana install under /plugins/Resources/Src/FnUsdAbstraction. This allows use of your own USD in place of Katana's FnUsd library for Native USD workflows. This does not replace the Hydra and UsdImaging libraries used yet.
If you utilise your own USD, you'll also need to rebuild KatanaUsdPlugins to ensure the USD data can be accessed when converting from in memory USD as part of the UsdProcessingEngine, and the UsdInOp used in the UsdToKatana node. If a custom Renderer is used as a Viewport Render Delegate, for importing/exporting USD material or light shaders via UsdIn, UsdToKatana or UsdMaterialBake; the NdrDiscoveryPlugin will have to be available to the KatanaUsdPlugins built against the external USD (for import/export via KatanaUsdPlugins), as well as FnUSD internal to Katana (for Viewer rendering).
In addition, a new CommonNodeInterface and common traversal system, which handles traversal of nodes implementing different processing trees was also added.
NodeUSD is a new Node class for handling USD Native processing andhas a similar interface as NodeGeolib3. NodeUSD nodes use the same Parameter setup, but instead of appending Ops to the OpChain, they append Engines to an EngineChainInterface via _getEngineChain. You may not mix Geolib Ops and USG Engines on the same node. However, you may use SuperTools to combine both. Engines take a set of EngineArgs which can be created using the helper class EngineArgsBuilder. This takes the frameTime, and is utilised when building multiple sample times for rendering and for the future, exporting.
A NodeUSDAPI was added as an interface to the USD Native logic. This can be used to get the UsgSceneManager, which provides access to the currently viewed USD Stage. Manual modifications to this stage will be lost when a re-composition is required by the Node Graph; thus a read only use case is best.
Addition of a new Engine Plug-in system
This allows building custom NodeUSD nodes and custom Engines, which are closely related to Ops in Geolib3, to enable studio specific capabilities to a native USD workflow. The core difference is that Engines will output their own SdfLayer rather than operating on individual hierarchy locations. An Engine can read its incoming Stage data if required, at the cost of additional compositions. This can be done by retrieving the sharedInputEngine(i) and requesting its rootLayer. We recommend masking this rootLayer when creating a stage for inspection, in order to reduce composition time and memory consumption. Engines can operate on a single time sample, or on multiple samples which will be provided by the EngineArgs. The time samples which need to be processed per engine evaluation can be retrieved from the GeomSceneContext.
Multi-Threaded Live Rendering Updates
Foresight+ Live Render updates are now generated using multi-threaded scene evaluation. This feature may be disabled by setting the KATANA_FORESIGHT_PLUS_RUNTIME environment variable to “classic”.
Cache Eviction Modes
The Geolib3-MT runtime can now use one of three distinct scene data management strategies, and defaults to one of the two new strategies. They are exposed in Render Settings as the following Cache Eviction Modes:
Properties of the New Modes
In addition to their own characteristics, the new cache eviction modes (‘Dependency protecting’ and ‘Continual’) differ from the existing (‘Relaxed’) mode in the following ways:
Removal of the Experimental Runtime
The Geolib3-MT (Experimental) runtime has been removed in favor of the above Cache Eviction Modes.
The version of 3Delight that bundled with Katana has been upgraded from version 2.9.8 to version 2.9.53. For more information, refer to the 3Delight for Katana Changelog.
The Katana Scene Delegate will now return light parameters via the `getMaterialResource()` as a `HdMaterialNetworkMap`, in addition to, the `getLightParamValue()` methods.
Toggling the Display > Default Lights checkbox supports removing and adding lights in the Viewer from the USD scene graph.
Objects from the Katana scene graph can be snapped to both Katana and USD Native scene objects.
Due to performance issues with terminal warnings from USD 23.05, `USD_SHADE_MATERIAL_BINDING_API_CHECK` has been set to `allowMissingAPI` by default. Any value set in the local environment will override this. Older USD Native USD stages missing UsdMaterialBindingAPI on Prims with `material:binding` will no longer create terminal warnings when parsing through the UsdImagingDelegate.
Toggling the View > Volumes checkbox supports volumes in the Viewer from the USD scene graph.
Support for Nuke 14.1 and Nuke 15.0 has been added to the Nuke Bridge.
Nuke 15.0 only supported since Katana 7.0.
The Render Settings have been extended to support the two new caching strategies for the Multi-Threaded runtime, Geolib3-MT. The new caching strategies are Dependency protecting (default), Continual and Relaxed (the default caching strategy available prior to Katana 7.0). The following new attributes and defaults are created to support these new caching strategies:
Shared:
For Dependency protecting:
For Continual:
Katana files created on versions prior to 7.0 will be upgraded to reflect the previous caching strategy to ensure functional equivalence. When loaded into Katana 7.0, cacheEvictionMode will be set to 'Relaxed'. The 'Geolib3-MT (Experimental)' runtime is no longer supported.
ID 524536 - Registering a custom, renderer-specific node (or SuperTool) in the Network Material context would prevent the Node Graph tab's layered menu from being populated with existing renderer-specific shading nodes.
It is now possible to toggle the splitter orientation in the Scene Explorer via the Katana or USD tree view header context menu. The splitter position and orientation is now saved in the layout.
The USD tree in the Scene Explorer tab now shows the pseudo-root ('/') as the root prim location.
WorkingSet instances can now be initialised with a given root path, defaulting to '/root', the Geolib root path, if not provided. It is now an error to use paths that are not part of the tree with the given root.
The default Katana layouts (Lighting, Lookdev, Monitor, Rendering) now include a Scene Explorer Tab over a Scene Graph Tab.
When the USD Visibility Working Set column is enabled, it applies Visibility rules and behaviour equivalent to that of the Katana Scene Graph. The states Included, IncludedWithChildren, Excluded and ExcludedWithChildren can be set at locations in this Working Set. Imageable prims at Included locations are visible. Note: Imageable prims at locations with Included descendants will be visible, regardless of their local rule.
When the USD Visibility Working Set column is disabled (default), only expanded locations will be visible in the viewer. Note that for instanced primitives, the location which defines the instance or instancer must be exposed for the instanced prims to be visible.
Render, Live Render and Visibility working set icons have been updated.
Icons in the Scene Explorer now convey working set state and USD native properties more consistently.
PyQt5 and PyQt5WebEngine updated to 5.15.9 and 5.15.6 respectively.
The blue sidebar on USD nodes would not dim with the node.
ID 373475 - Graph State Variable parameters wouldn't respect the 'widget' hint string if supplied.
A new 'hiddenVariables' parameter has been added to the root node and the Project Settings tab. It accepts a comma separated list of variable names which you want hidden from the UI.
UsdIn* nodes have been to moved to a 3D Nodes > UsdIn category and all USD Native nodes are now categorized under a USD Nodes heading
ID 533271 - When prim's purpose attribute was set to "guide", visibility was set to on(1).
Katana has been upgraded to use USD 23.05 by default.
When baking materials with UsdMaterialBake node, MaterialBindingAPI was not applied to the Prim with the material binding Relationship.
The UsdPythonWrite node no longer shows up in menus unless the environment variable KATANA_ENABLE_USDPYTHONWRITE_NODE is set to 1
A describe() method has been added to the Engine class to summarise a USD Native Engine and its arguments. The EngineRegistry class can describe any Engine and serialise it to a string in the JSON format.
The EngineRegistry instance was added to the UsdProcessingEngine Python Module with two methods available:
- getAllEngineNames() and describeEngine(engineName)
usd context has been added to aid in AssetAPI implementations when dealing with paths which will be parsed by USD's AR Resolver within the Native USD toolset. It is also accessible via the constant in `FnAssetSuite`, `kFnAssetContextUsd`.
A new UsdPrimvarSet node has been added to provide an easier way of setting prmvar data on prims.
Additional list editing options have been added to some of the composition nodes to allow the user to "reset to explicit" and "delete". These options are to supplement "prepend" and "append".
UsdPrimCreate did not account for each Attribute's variability definition from the schema, and would set time samples for Attributes specified as uniform by the schema.
Use the usdSceneExplorerLocationArray widget hint to enable similar functionality for importing and exporting selections to the existing scenegraphLocationArray widget for the USD section of the Scene Explorer tab.
ID 471827 - UsdLux radius/size/length attributes imported with UsdIn node did not work
ID 555499 - Deletion of Render Catalog Items did not free image memory, neither immediately, nor during interprocess garbage collection (the time interval for which is set by KATANA_INTERPROCESS_GC_TIMEOUT_SECONDS, defaulting to 30 minutes).
ID 540205 - When adopting a template material for editing in one GafferThree node from another GafferThree node, the template material would not become editable and an error message would be logged in the Messages tab.

ID 541856 - When a parameter in a node type configured with the EnableableParameterPolicy was deleted while being visible in a widget and set to show the node's default value, a crash could occur.
ID 538939 - Live Renders would become unresponsive and stop processing updates following a change to the render camera.
ID 551504 - Flushing caches during a Live Render would cause error messages to be printed and the Live Render to stop responding to updates.
ID 552996 - Geolib3-MT in 'Dependency protecting' cache eviction mode could fail to protect the last cooked location's scene data from time-interval-triggered eviction.
ID 553343 - Geolib3-MT in 'Dependency protecting' cache eviction mode could clear all scene data on eviction when Op Tree Optimizations are enabled.

ID 411783 - When triggering LiveGroup pre and post publish callbacks, the behaviour was inconsistent between them being triggered in the UI and through Python.
ID 505743 - Updated usage of PyQt to remove implicit conversions of float to integers.
ID 542592 - When using Katana with a Python 3 version, Python parameter expressions with some mathematical (>=, <=, >, <, ^, &, |, >>, <<) operators would fail. (This issue is a regression in Katana 5.0v1.)
ID 544072 - A tooltip now appears when you hover the mouse over the headers of working set columns in the Scene Explorer tab, which provides a brief description of their respective functionality.
ID 544716 - When Katana was closed with a detached Scene Explorer tab, a QBasicTimer warning was displayed.
ID 546072 - Render Only Selected Objects now renders children of the selected locations. This is equivalent behaviour to the Scene Graph tab.
ID 546301 - USD locations with payloads are now shown in the Scene Explorer tab's search results, regardless of whether they are loaded.
ID 547266 - Selections in the Scene Explorer tab wouldn't highlight the entire row.
ID 550807 - The Scene Explorer tab would attempt to search for locations when typing after it has focus, this interfered with other hotkeys, such as for framing to the current selection in the Viewer tab ('F').
ID 552053 - Restoring a USD or Katana view after loading a saved layout where it was collapsed no longer results in a hidden view or unexpected behaviour.
ID 552251 - USD Native light visibility did not update on changes to Viewer Visibility scope.
ID 554180 - The USD Viewer Visibility Working Set did not respect the Excluded state on descendants of locations with the IncludedWithChildren state.
ID 522847 - Attempting to Resize All to Contents in the Scene Graph tab's header would emit Python deprecation warnings.

ID 544721 - Changing the Parameter Hints on a Parameter using the ArrayFormWidget from being resizable to being of a fixed size caused the UI to incorrectly still show a scroll bar which when scrolled would cause index errors.
ID 549487 - Existing native USD nodes have changed their flavor from usd to nativeusd. Nodes which exhibit the nativeusd and not the 3d flavor are displayed with a blue sidebar. New native USD nodes need to be registered with the nativeusd flavor to display correctly.
ID 551320 - The node color picker would raise an exception or deprecation warning.
ID 513811 - Removed error message caused by adding custom columns to the SceneGraph. (This issue was a regression in Katana 5.0v1.)

ID 554192 - The Viewer tab was not respecting the Visibility attribute of USD prims in Katana.
ID 544535 - The key tokens for conditional visibility for node parameters were incorrect in the dev-guide.
ID 549588 - When changes in the type parameter in UsdPrimCreate were undone, unexpected undo entries could be inserted in the undo history.
ID 114182 / BZ 49288 - When exporting a Catalog item you need to specify the export folder path to an existing folder. If the folder you're trying to export to does not exist on disk Katana will fail to export. (This issue is a regression in Katana 2.0v1.)
ID 427252 - Locators created via PrimitiveCreate nodes can be snapped to in all modes, rather than just the Lights, Cameras, and Locators mode.
ID 420882 - Changing between the Viewer (Hydra) tab's multipane layout options quickly can cause a crash or many error messages to be written to the terminal/console.
ID 380129 - Use of non-conformant GL anti-aliasing modes that employ supersampling reduces rendered point size by the supersampling scaling factor. Katana currently employs any reported anti-aliasing mode (up to a maximum sample count of 16): as a workaround, change the viewerHydra.antiAliasing preference to a lesser anti-aliasing mode.
ID 352167 - Textures loaded from Hydra shaders are not cleared or reloaded from disk when flushing caches.
ID 85118 / BZ 41152 - When editing parameters of a node that is part of a LiveGroup node and reloading the parent LiveGroup node, the UI state of the Parameters tab is reset. This includes scroll bar positions, selections of items, and selections of nested tabs (for example Object, Material and Linking tabs for a Gaffer node).
ID 84998 / BZ 41092 - When reloading a LiveGroup node's parameter interface and contents from its source, parameters of child nodes that are edited in floating panes disappear from those panes.
ID 84020 / BZ 40598 - Reverting a LiveGroup node does not revert its user parameters.
ID 84018 / BZ 40600 - Undoing a revert of an unpublished LiveGroup node does not restore the LiveGroup's editable and modified state.
ID 83061 / BZ 40237 - Nodes can be dragged into the Group bubble of a non-editable LiveGroup node.

ID 429775 - NetworkMaterialEdit nodes do not currently respect local Graph State changes, for example as performed by VariableSet nodes downstream.
ID 429302 - When editing a locked node inside a NetworkMaterialEdit node graph, the parameters will be shown at their default state.
ID 427408 - When entering a NetworkMaterialEdit node whose sceneGraphLocation parameter is empty, warnings are logged by the Geolib3 Runtime.
ID 423341 - In a NetworkMaterialEdit node graph, connections can be displayed incorrectly if a node's name begins with a number.
ID 402064 - In a ShadingGroup node graph, the connection between a Dot node and a shading node port can be wrongly colored in some cases.
ID 269449 - Choosing Edit Shader Parameters from the main wrench menu of Material nodes does not show wrench buttons next to shader parameters. This can be worked around by toggling the edit flag on the node. (This issue is a regression in Katana 2.5v1.)
ID 199304 - The namespace parameter on Material nodes wrongly allows the insertion of Unicode codepoints outside the ASCII range.
ID 191052 - Katana does not have any support for the texture reference object workflows of V-Ray for Maya.
ID 188533 - Expressions linked to non-local parameters on not previously edited Material nodes can't be evaluated.
ID 105434 / BZ 47520 - Reference Expressions may not refer to dynamic parameters such as shader parameters.
ID 60457 / BZ 31790 - Setting an array or group parameter to an expression results in an invalid expression. Upon setting a valid expression (for example, an evaluation of an equivalent parameter on another node using getParam), the parameter is not immediately updated. To workaround this issue, close and reopen the parameter, or flush caches while the node is not edited.
ID 105424 / BZ 47518 - Expressions using getParam to link to dynamic parameters would fail if the dynamic parameters hadn't yet been cooked.
ID 496659 - When loading a website into a PyQt5.QtWebEngineWidgets.QWebEngineView widget, warning and error messages may be issued by the underling Qt WebEngine classes, leading to certain websites not being displayed correctly, or not being displayed at all. (This issue is a regression in Katana 4.5v1 / Katana 5.0v1.)
ID 494168 - In the Katana Developer Guide, some members of C++ classes that are marked as friend incorrectly appear as friend friend. (This issue is a regression in Katana 5.0v1, and may be related to an issue in Breathe.)
ID 524428 - Misleading error messages can be shown in the Render Log when live rendering with 3Delight.
ID 523574 - Sourcing an aces v1.3 colour profile can cause Katana to crash when rendering with renderer plugins that don't currently support aces v1.3
ID 381284 - The 3Delight renderer plug-in makes use of source material locations rather than resolved material attributes as a means of de-duplication. This can result in material data being lost when excluding material locations from the Render Working Set during a Live Render session.
ID 176598 - Use of nodes that modify Graph State Variables in Interactive Render Filters is not currently supported.
ID 74799 / BZ 36926 - The rendererSettings > displayOptions parameter of a RenderOutputDefine node for the PRMan renderer, shown when its type parameter is set to 'raw', cannot be set using the Parameters tab.
ID 70217 / BZ 36176 - The 2D node Disk Render Upstream Render Outputs option does not use the batch render method, batchRender, for upstream render nodes, instead using diskRender.
ID 70016 / BZ 36137 - Rendering repeatedly with a large number of AOVs consumes more and more memory, possibly leading to a crash when running out of memory.
ID 12517 / BZ 16168 - Only one Monitor tab may display the results of a Preview Render. The use of multiple Monitor tabs is not currently supported.
ID 373702 - Clicking in the Viewport and pressing a shortcut whilst the mouse is hovered in another widget will still send the event back to the 'focused' Viewport widget, for shortcuts where the widget hovered over does not handle the shortcut.
ID 208802 - Closing the Histogram tab after use leaves the Monitor tab unable to display rendered images.
ID 123558 / BZ 50911 - When changing an array parameter's tuple count/size, any corresponding attributes are not properly updated in the Attributes tab.
ID 112544 / BZ 49051 - The Viewer tab may lose sync with the Scene Graph tab when changes to expansion state are interrupted.
ID 107038 / BZ 47853 - Indication of attribute source nodes (such as the yellow 'glow' in the Node Graph tab) is unavailable as of Katana 2.0v1.
ID 71965 / BZ 36691 - State badges are currently shown for attribute values of dynamic array child parameters, even though only their parent array parameter should appear with a state badge.
ID 65347 / BZ 34949 - Using Compiz can lead to text fields not receiving focus events correctly due to an incompatibility between Compiz and Qt. Depending on your configuration, disabling Compiz "desktop effects" may resolve the problem.
ID 468287 - UsdIn is not retaining expanded view state information for shading nodes in a Network Material context.
ID 381692 - (Windows only) When logging out and logging back in again, the colors in the UI are incorrect. For example, certain parts of certain types of tabs may appear with a white background color. (This issue is a regression in Katana 3.1v1, possibly caused by QTBUG-52728 - Paint bug and palette errors after some events in Windows)
ID 344118 - (Windows only) When installing Katana and opting to install the bundled version of 3Delight, the installation of 3Delight is made by modifying system-wide environment variables such as KATANA_RESOURCES. Thereafter, launching any version of Katana will pick up this installation of 3Delight, which may be incompatible with the version of Katana being launched.
ID 218742 - (Windows only) Katana must be installed to a path no longer than ~140 characters. Attempting to install to a longer path results in an unintuitive error: "The system cannot find the path specified."
ID 84326 / BZ 40709 - The Alembic library does not support multiple process or thread access to an Alembic file. This means that a crash occurs when modifying an Alembic file outside Katana, while it's loaded in an open Katana scene. To avoid this, you must Flush Caches before attempting to update any modified Alembic files.
ID 80738 / BZ 39261 - Operations that lock and unlock nodes do not currently create entries in the Undo History, which can lead to an incorrect node graph state when undoing and redoing operations.
ID 70196 / BZ 36170 - Control keys (notably arrow keys) do not function as expected in shell mode.
