I am working on a little script to add a node or two into a material setup and have come across something that has my head aching.

With the diffuse color it works.

diffCol = root.InputByInternalName("Diffuse_Color")
nodeindiff = diffCol.InNode();

but I cant get it working for Alternate Diffuse

altDif = root.InputByInternalName("Alternate_Diffuse")
nodeindiff = altDif.InNode();

Whether I have a node plugged in or not, it returns an error:

AttributeError: 'NoneType' object has no attribute 'InNode'

It's of course possible that the alternate diffuse doesn't have an InNode method.  I'm not especially familiar with the Poser Object Model, but it seems logical that if Diffuse Color has it, then the Alt would have it too.

Any ideas? or is there another way I can identify the node plugged into Alt Diffuse.

Many thanks

John.
