I have a script which adds an image node to the bump/displacement nodes and sets the values, which works perfectly fine. What I can't get it to do is set the gamma on the image node to 1 and the filtering to crisp. Yes, I know there are scripts which will do that for me (and I have them), but I'd like to incorporate it into the script itself so I don't need to do the additional step.

This script will give you the internal name and value for every input in every node in your shader tree (edited version of a PrintShaderTree.py from the old (now defunct) DAZ forum archive):

import poser
tree = poser.Scene().CurrentMaterial().ShaderTree()
for n in tree.Nodes():
    print 'nNode ',n.Name()
    for i in n.Inputs():
        print '- ',i.Name(),'(Internal name=',i.InternalName(),', value=', str(i.Value())

I''m running Poser 9 at present so I used that script to get the Filtering parameters for you - it has internal name 'Filtering' and the numeric values are None = 1, Fast = 2, Quality = 3, and Crisp = 4

You can run the script to get the gamma details (Poser 9 doesn't have gamma)

As far as I know PoserPython doesn't have built-in enumerations fro the drop-downs in material room nodes, but I'm fairly sure that they're integer values in order starting at 1 for the top item in the list

To set the filtering value of node 'n' to Crisp you'd simply do:

n.InputByInternalName('Filtering').SetFloat(4.0)

Thank you.
