Vray Mesh material slots to vray shaders

[cgdom]

Is there a tool that comes with v-ray or a script that someone has made which will take all the material slots that come in with a v-ray proxy and the vray mesh material, and auto attach v-ray materials with them same names ? I want to be able to click on the names in the shader list (or scan the whole list) and get a bunch of attached vray mats ready to be worked on.

Another way (maybe better) would be to have a tool that looks at materials by the same name in the scene and auto attached them to all the slots on the selected vray material node.

Here is a method that connects shaders with identical names to the VRayProxyMaterial.

def assign_shader(self, vray_proxies, *args):
'''
This method connects shader with identical names to the vrayProxyMtl.
The shaders have to be in the scene. They can be loaded as a reference but must have the same namespace as the target vraymeshmtl.

Args:
vray_proxies: list of vray proxie nodes
'''

for proxy in vray_proxies:

    # test if node is VRayMesh
    if cmds.nodeType is not "VRayMesh":
        continue

    vrproxy_material = cmds.listConnections(proxy + '.fileName2', type='VRayMeshMaterial')[0]

    proxy_namespace = proxy.rpartition(':')[0]

    cmds.setAttr(vrproxy_material + ".assignShadersByName", 1)

    for index in range(0, cmds.getAttr(vrproxy_material + '.shaders', s=True)):
        shader_name = cmds.getAttr(vrproxy_material + '.shaderNames[{}]'.format(index)) # short shader name
        full_shader_name = proxy_namespace + ":" + shader_name # full shader name with namespace

       # check if shader exists in scene
       if cmds.objExists(full_shader_name) == True:
       # and then test if it is already connected
       if not cmds.isConnected(full_shader_name + ".outColor", vrproxy_material + ".shaders" + "[" + str(index) + "]"):
           # if not, connect it
           cmds.connectAttr(full_shader_name + ".outColor", vrproxy_material + ".shaders" + "[" + str(index) + "]", f=True)
       else:
           # If the shader does not exist, let the user know which shader
           print "Shader {0} is missing!".format(full_shader_name)

Thank you, unfortunately I must be doing something wrong because I get a "// Error: Line 1.23: Invalid use of Maya object "self". // " error when I try to run the script. Do you know what could be wrong ?

The snippet is from a larger script with a class. It needs to be called in a class with a list of nodes as an argument.
