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. 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 an 'ai' suffix will be added to the shader name.


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