New Features in 23.5

  • The forcepar option is now available on the RenderOutputDefine node for raw and deep EXR outputs

  • Added new volume primAttributes to PrmanObjectStatements
  • The new shadowthreshold parameter is now available in PrmanOutputChannelDefine
  • Support for new menus in Katana 4.0, allowing native workflows
  • RfK now supports adding/removing outputs when live rendering to the Monitor in Katana 4.0+. This behavior was previously only supported when rendering to “it”

Known Limitations

Live Rendering

  • Changing the cameraName in RenderSettings doesn't update AOVs without a specified camera

  • 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

  • Live render edits to the visible attribute need group locations to be "included with children" in the Live Render Working Set

RenderMan for Katana

The Monitor doesn't support adding/removing displays during a live render

  • If you use ROI and overscan or cropWindow, the ROI will have to be adjusted slightly after a resolution edit to get the correct value during a live render
  • 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.
  • 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.
