Enhancements

  • Updated Arnold core: Update to Arnold 6.0.1, which features GPU support for light filters, energy-preserving rough refraction, improved Oren-Nayar diffuse and rough thin-wall transmission, improved license management, and much more in addition to many bug fixes.  Please see the release notes here. (#434, #419, #437)

  • Katana 3.2 support: Katana 3.2 is now supported as an official host. (#412)
  • MaterialX material export: In addition to baking MaterialX looks, the ArnoldMaterialXBake node can now bake materials, e.g. the surface/volume and displacement shaders attached to a shape, into a named material in a MaterialX file. ArnoldMaterialXAssign also more clearly differentiates between a material and a look being assigned. (#431)
  • MaterialX assign improvementsArnoldMaterialXAssign now allows selecting a specific material out of the file, rather than relying on the presence of entire looks. (#419)

  • Enhanced license management: New and improved license management app. (#408, #427, #336)
  • Improved GPU device selection: The manual GPU device selection (in the device area of ArnoldGlobalSettings) is improved, and error reporting when GPUs cannot be used has improved in the log. (#410)

  • Curves user data improvements: User data on curves is now properly handled, even when triplicating endpoints for B-spline and Catmull-Rom bases. There is also a new operator/node for manipulating curve widths more easily, ArnoldCurveSetWidth. (#421, #380, #391)

  • Installer: KtoA now is officially distributed via an installer on both Linux and Windows, with binaries signed on Windows as authentic Autodesk products. For custom/local builds the old zip and tarballs can still be generated, however. The installer will try to find (and allow the user to set) the katana location, so that it can generate a launch script which makes it much easier to run KtoA. For power users they can still use their existing launch setup for Katana, setting KATANA_RESOURCES, etc as before. (#309, #429)
