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.
