Shader Conversion Script

To convert existing assets from Maya or mental ray to Arnold for Maya, a sample conversion script is available in the \docs directory of the MtoA installation folder. For example, in Windows it would be here: 



This simple script converts unsupported materials (Phong, Blinn, mia_material, etc..) to an Ai Standard shader.

  • 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 shaders, and a 'ai' suffix will be added to the shader name.


The converted Standard shader will approximate the attributes of the Maya shader.
