Quote - Sorry Tiny, I was trying to picture it in my mind's eye and memory.  Click on "Add Material Zone".  That will create the Template necessary for assembling your nodes.  Glad I saw this before log off.  Keep us posted if you have problems; glad to help.

No problem at all. Thanks, that did it!

Quote - - Very Important: your Hair rules should be named for all the material parts of your hair.  You can use wildcards to generalize the names, but must pay strict attention to all the parts.  All hair are not constructed the same.

This is dynamic hair and I don't have material parts on it but I do have 42 hair groups, associated with each body part, named for example hip_1, head_1, etc. Do I need to create a rule for every hair group (42 of them)? They all have the same settings. Would be good if there was a "general rule" for all the hair groups.
