Substance Painter importer 1.0.0 for Maya (maya script)

Hi, I was trying to use your script but I couldn't actually get the textures to get connected and any objects that are processed are reaplced by a shader list node -the object disappears from the scene!

The interface for the script loads correctly and I followed the directions (selecting texture path, following name conventions, selecting the materials and then hitting the create materials button). I also made sure that there were no name problems on the shader groups.

this is the error:

line 561, in arnoldImport
#     cmds.connectAttr(materialNode + '.outColor',shadingGroup[0] + '.surfaceShader')
# TypeError: 'NoneType' object has no attribute '__getitem__'

Has anyone else reported this issu?

Hope this helps!
