hborre, thanks for helping out. Picture show what it looks at at my end.

I'm not getting the new rule on my material dropdwon list. There must be a step I'm doing wrong.
I run the Python VSS main button script
In Material room I select the VSS prop
Click the Designer... button on Python scrip
Click the Add a rule node (there is no button with the name Templet rule)
Make a node named Hair - A node is created  but nothing in the dropdown list

Where do I go wrong here?
