New Features:

  • Blender 3.6 and 4.1 are now officially supported. Note, the Qt framework is not supported in 4.1
  • Viewport renders can now use the RenderMan AI denoiser as well as the OptiX denoiser. See the Blender denoising page for more information.
  • Add a new menu item in the shader graph to convert selected Cycles image nodes to PxrTexture nodes. This is useful when dragging and dropping image files from the file browser to the shader graph.

Changes:

  • We now pay attention to the Viewport and Render levels when using the subdivision modifier. Note, the subdivision scheme setting on the object data properties still takes precedence.
  • A new json filename statistics option has been added to the workspace editor. This should be used in favor over the older XML filename.
  • The drawing the barn light filter projection in the viewport when in physical mode has been disabled
  • A LamaSurface node will automatically be created for you, when attach a Lama node bxdf to your object.
  • The addon will now present a dialog when importing presets that include display filters.
  • The "volume:temporalmethod" primvar has been removed.
  • The package scene operator will now print an error message if the directory selected is not empty.

Bug Fixes:

  • Fix a bug where importing presets with array parameters failed.
  • Fix the orientation of the PxrEnvDayLight. The sun was rising and setting in the wrong directions. Note, older scenes will change with this fix

  • A bug that caused "it" to display the wrong Pixel Variance value when rendering with IPR has been addressed.
  • A bug that caused PxrRamp nodes to not update during IPR when they are inside of group nodes has been fixed.
  • A bug that caused assets to fail to export in the preset browser, when you have a color to float connection has been addressed.
