Miscellaneous Changes

• Alembic_In_Prman has been deprecated in favor of the default Alembic_In node. It has been removed from the Tab and Importomatic menus, but existing nodes will still work.  The shelf script Alembic_In_Prman -> Alembic_In can be used to replace all Alembic_In_Prman nodes with Alembic_In.

• If an interactiveOutput is added in RenderSettings, but doesn't have a corresponding RenderOutputDefine, we no longer render that display.  Previously, such displays would default to Ci,a.

• Live render edits to orthographicWidth are now supported.  This enables zooming Katana cameras with orthographic projection during live render
• New hider options:
  • adaptivemetric - Specifies the metric used to drive adaptive sampling.  The Pixel Variance default changed to 0.015 to align with the new default "variance" adaptivemetric
  • decidither - When making rapid edits to heavy scenes and this setting is non-zero, the renderer will try to reduce tearing by updating the whole screen progressively with a dissolve-like effect
• Updated the values set by the Quality Preset parameter in PrmanGlobalStatements
• OSL options moved from prmanGlobalStatements.options.user to prmanGlobalStatements.options.osl.  Old PGS nodes should update automatically

• The integrator parameter "maxPathLength" has been renamed to "maxIndirectBounces" to be more descriptive and unified across integrators. The new setting is one less than the original value for PxrPathTracer and PxrVCM. The PrmanIntegratorSettings node automatically upgrades the parameter to the new name and value, but users who have directly set the attribute should update their scenes.

• The master attribute, curve:opacitysamples is now available in PrmanObjectStatements

• The preset browser will now drop nodes in the current group node when importing an asset

• Disable Local Assignment now works during live rendering for editable prmanGlobalStatements - min/maxsamples, decidither, and PixelVariance

• There is now an option in PrmanGlobalStatements for rendering raw checkpoints to the tempRenderLocation in the RenderOutputDefine node, rather than rendering them to the final renderLocation.

• Examples directory fixes:
  • The image plane texture for the holdout example is now packaged in Examples/assets/textures
  • The example katana files that use Katana's house xml now find the asset via the KATANA_ROOT environment variable.

Bug fixes

• Fixed a bug where prmanStatements.primAttributes.trace.displacement would automatically be set to the default value of 1 if other prmanStatements were set at that location
• RfK now captures edits to lights that happen between the time the live render starts and when the light location is added to the live render working set
• Fixed a potential crash for scenes with cameras that aren't used in a Display
• Warnings set with the "warningMessage" attribute are now correctly output to the render log
• Fixed a crash for polygons when the number of tuples in the vertexList is greater than 1
• Light filter linking now works for PxrBlockerLightFilter and PxrGoboLightFilter
