# Katana 7.0v8 Release Notes

# Release Date

06 October 2025

# Previous Releases

- Katana 7.0v7 Release Notes

# What's New in Katana 7.0

These release notes describe changes from Katana 7.0v7 to 7.0v8.

For a high-level overview of important changes in the Katana 7.0 line, please see the accompanying What's New in Katana 7.0 document.

# Feature Enhancements

## Network Materials

- ID 592909 - Pressing and holding the 'W' key on a collapsed Shader node in the Node graph will temporarily expand the node. It will return to it's original state when 'W' is released.

## USD Import

- ID 600172 - The ids attribute are now being converted and can be found in the Attributes tab when loading in point instancer scene locations through the UsdIn node.

- ID 605970 - The UsdIn node assetResolverContext parameter has been upgraded to assetResolverContexts and been upgraded from a `string` to a `stringarray` parameter. The upgrade script can be found in the KatanaUsdPlugins repository.

  If you build a custom KatanaUsdPlugins, it is strongly recommended to cherry pick the changes if you plan on using Katana 6.5v8, 7.0v8, 7.5v5 or 8.0v5.

  The internal Katana document version for this change is 7.0.5.2.

# Bug Fixes

## Miscellaneous

- ID 598531 - When expanding the LookFileManager passes, an error would be logged.

- ID 600459 - When using a system with an AMD graphics card, shading nodes in NetworkMaterialCreate or NetworkMaterialEdit contexts were not drawn properly.

  AMD graphics cards are not officially supported for use with Katana.

- ID 604815 - When a Disk Render with allowConcurrentRenders enabled was queued twice in rapid succession, the UI became unresponsive.

## Network Materials

- ID 592908 - When in the Network Material context and hovering over a connection noodle, middle mouse pan action would not work.

## Rendering

- ID 514871 - When using Extended ASCII characters and performing a Batch Render, UTF-8 decoding errors were being raised.

- ID 601075 - When a Live Render (Foresight+) was started with the Region of Interest (ROI) enabled, a null region could be delivered to the render plug-in if the creation of the associated Catalog Item was slightly delayed for any reason, leading to a render that does not show any pixels until the ROI is tweaked by the user.

  The issue was first seen when RenderMan's interactive denoiser was set up.

- ID 602034 - When using the Arnold viewer delegate, monolithic materials would not display in the Viewer tab.

- ID 602766 - When Katana received image data for a render output that is not currently enabled, new 'External Render' Catalog items would be created for individual render outputs. For example, this would occur when adding AOV passes through InteractiveRenderFilters during a live render.

- ID 606538 - When renderers exited with custom error codes, Katana would always return a -1 error code.

## UI

- ID 599701 - When doing a right click action in a Supertool's Parameters tab, the menu would be misaligned with the cursor.

- ID 602457 - When attempting to inspect signature of a callable object without having one, a ValueError exception would be raised.

## USD Native

- ID 598468 - When using left mouse double click expansion on USD locations in the Scene Explorer tab, all locations would be expanded ignoring stop types, such as assembly, component and subcomponent.

- ID 603323 - When a material was bound to a prim directly under a PointInstancer prim, UsdIn nodes failed to correctly construct the hierarchy of the PointInstancer.

- ID 605084 - When using the UsdActiveSet, UsdInheritSet, UsdPayloadSet, UsdReferenceSet, UsdSpecializeSet and UsdVariantSet nodes, the prim type was not correctly exported.

## Viewer

- ID 607430 - When switching to the AVP Render Delegate in the Viewer tab, Katana would crash. This was a regression in Katana 7.0v7 that only affected this product line.

# Known Issues

## Hydra Viewer

- ID 580249 - When manipulating transformations for both Geolib and USD locations/prims at the same time, the manipulator handle will ping to the center of the USD mesh.

## USD Native

- ID 588881 - The pivotTranslate parameter on the UsdTransformEdit node currently have no effect.

- ID 587515 - The Centre of Interest manipulator is currently not supported in conjunction with USD prims.

- ID 586965 - USD's stitch method for stitching layers doesn't retain blocked attributes.

- ID 579376 - Currently, Pattern-Based Collections does not support the use of the include and exclude widgets in conjunction with the membershipExpression widget on the UsdCollection node. This is due to a known issue with USD 24.05.

  Note: More info can be found on the USD thread: https://forum.aousd.org/t/problems-with-pattern-based-collections/1197/7. Katana's Pattern-Based Collection widget computes collection membership using membership expressions, therefore it does not currently handle relationship-mode collections correctly (statement true for USD 24.05).

## Miscellaneous

- ID 605164 - There are data size limitations when using the `policy/xml` MIME data format in UsdAttributeSet. The limit can be changed using the `KATANA_VALUEPOLICY_MIMEDATA_ARRAY_SIZELIMIT` environment variable, but increasing that value could cause performance issues when large Array attributes are copied.
