Rendercore Lab Now Supports Arnold 3.1.2 for Maya!




  • New aiOsl shader, that allows to write inline osl code and use it in a shading tree.
  • Added Sheen parameter in aiToon and in the list of AOVs.
  • Added "Azimuthal Roughness" to aiStandardHair.
  • Added Velvet preset for aiStandardSurface.
  • Fixed crash when assigning a shader to a custom shape procedural.

RenderView / IPR

  • Always add default persp camera to the list of available cameras in ARV.
  • Fixed error "Arnold RenderView is not unique" that could prevent from using ARV when opening an existing scene.
  • Removing objects inside Render Setup collections wasn't refreshed in IPR.
  • Enabling / disabling collections from Render Setup wasn't refreshed in IPR.
  • Deleting an assignment in aiSetParameter wasn't refreshed in IPR.


  • Added arguments to Maya batch render to output Stats and Profile info.
  • Set Overrides were not working on Standins.
  • Upgraded Cryptomatte to 1.1.0 which contains the fix: "Preview AOVs are now always displayed in display drivers, even when previewinexr is disabled".
  • Upgraded OIIO (2.0.1) and OSL (1.10.1).

Incompatible Changes

  • Curves first segment wasn't rendered with the right amount of CVs. This was mostly visible for low samples and is now fixed. Existing scenes might, therefore, render differently.
