MtoA 3.1.0 is a feature release, including the following improvements:

Shader Improvements

  • Added sheen parameters in aiStandardSurface.
  • Added new cell noise shader aiCellNoise.
  • Cryptomatte shaders are included by default with MtoA.
  • aiToon can compute the edge detection based on custom toon_id value when it's set on the shapes.
  • New Matrix shaders.

Arnold RenderView

  • Added progress bar to the renderview.
  • Improved feedback in the status bar, about what is being processed by MtoA.

Standins

  • Added parameter "operators" allowing to apply operators to a specific standin only. The selection string must refer to the nodes inside the .ass file.
  • Show the contents of the .ass file in the Standin Attribute Editor, and allow to apply overrides on the selected items.
  • Stabilized the VP2 display of Standins, including if a render is in progress.

Render To Texture:

  • Added option "extend edges" to fill texture seams.

Other

  • Improved the quality of both noice and optix denoisers.
  • Added menu in "Arnold->Utilities" to Export / Import operator graphs.
  • Maya shaders "checker", "multiplyDivide", and "clamp" are now being exported as Arnold native shaders.
  • Fixed IPR updates of XGen splines.
  • Improved Arnold area lights illumination in VP2.
  • Bifrost foam can be rendered with both a surface and a volume shader.
  • Extended the menu "Arnold->Utilities->Convert Shaders to Arnold" to support the following utility alShaders : alLayer, alLayerColor, alRemapColor, alRemapFloat, alFractal, alFlake, alLayer. A basic support of mia_material, dielectric and VrayMtl is also included.

 

Incompatible changes

MtoA 3.1.0 is not binary compatible with 3.0.* versions. All 3rd party extensions, shaders, and procedurals will need to be recompiled against the latest version.
