Miscellaneous Changes

• Hydra Viewer improvements:
  
  • The PxrEnvDayLight sunDirection parameter now has a manipulator
  • The Refine Shape and Scale Edges manipulators for PxrRodLightFilter are now available
  • Viewer Manipulators now display annotations
  • Prevented the default Katana light locator from drawing when a light filter is added to a light
  • The PxrPortalLight and PxrDistantLight guides are now distinct from the PxrRectLight and PxrDiskLight representations
  • It is now easier to select lights
  • We now hide the analytic cookie manipulators if the cookieMode is "physical"
  • The width and height controls on the Barn Size manipulator now match line up with the BarnLightFilter visualization
  • The Rod Scale, Cookie Scale, and Barn Scale manipulator handles will now remain orthogonal no matter how the light filter is transformed
• The RenderMan built-in error handlers are now fully supported (prmanGlobalStatements.errorHandler). This has been extended to include a new handler 'abortall' which indicates the render should be terminated on a katana error
• All provided shaders with a ramp UI now allow a dynamic number of knots
• RfK no longer outputs uninitialized values to PxrRamp's colorRamp parameters
• Deleting primvars and primAttributes now updates in Live Render
• RfK no longer adds "origin" and "OriginalWindow" to the display lines. These values are properly computed by prman
• RfK's display option configuration has been adjusted to align with prman's expectations for crop window and overscan

Fixes

• Fixed live render crashes when deleting or renaming a light
• Fixed an error messaged that was displayed when "Tab" was pressed in the Hydra Viewer when a light with no manipulators was selected
• The Scale Edges manipulator for PxrRodLightFilter in the Viewer are now correctly positioned when the scaleWidth, scaleHeight, and scaleDepth parameters are non-default
• Fixed a bug where a parented, shared light filter using the "Light + Light Filter" Coordinate System was not drawn in the Viewer and Hydra Viewer
• Fix a bug that would cause "point" output channels to be emitted with type "int"
• The UI default value for the Visible In Refraction parameter on lights now matches the default in the renderer
• The preset browser tab works again

• Addressed a bug with the preset browser where  exporting light rigs and materials from a parent group failed

• The preset browser now supports array and dynamic array parameters.  Materials that use PxrRamp can now be correctly saved and imported
• The autocrop option on RenderOutputDefine for raw OpenEXR renders now works

Miscellaneous Changes

Fixes

Live Rendering

• Creating a mesh light from existing geometry will duplicate the geometry in-render. Restart the render to remove the duplicate.

• Cannot change a geometry primitive type during live rendering (e.g. from NURBS to polymesh)

• When assigning a material to a Scene Graph location, that location must be enabled in the live render working set

Katana Limitation

• Instanced lights with filters using the "Light Filter" coordsys have an incorrect transform. The workaround is to promote the light filter to a shared light filter using a light filter reference.

• When rendering to "it" from Katana, do not stop the render from "it", abort the render from Katana. Your Katana session may freeze for a time if you abort from "it". If you make this mistake you can restore Katana to operation by terminating the prman render process manually. This will be fixed in a future version. You can also avoid this entirely by rendering to the Katana Monitor.

• We do not receive live render edits from Katana for nodes added at the end of the node graph, right above the Render node.  If a no-op node (e.g. Merge) is inserted above the Render node and the node is added above that then the edit is received.
• Any live updates will cause interactive motion blur to be disabled. The render must be restarted.
• PRMan error handlers are not fully supported yet.
• Instanced lights with filters using the "Light Filter" coordsys have an incorrect transform. The workaround is to promote the light filter to a shared light filter using a light filter reference.
• There are a few live render limitations in Katana 2.6 that have been resolved in Katana 3.0 based on the improvements to 3.0, typically limitations with live working sets and adding/deleting locations in 2.6
