Convert Shaders to Arnold

Use this to convert existing assets from Maya or mental ray to Arnold for Maya.

Shader Conversion Script

A sample convertShaders.py conversion script is also available in the \scripts directory of the MtoA installation folder. For example, in Windows it would be here: 

scripts\mtoa\convertShaders.py

 

This simple script converts the following shaders to a standard_surface shader:

aiStandard, aiHair, alSurface, alHair, alLayerColor, alRemapColor, alRemapFloat, alFractal, alFlake, alLayer, lambert, blinn, phong, VRayMtl, mia_material_x_passes, mia_material_x, and dielectric_material.

  • Load the script (as a Python file *.py), and the following message should appear.
  • Choose to convert all of the shaders or just those selected in the Hypershade window.

 

The Maya shaders will be converted to standard_surface shaders and will approximate the attributes of the Maya shader.
