Thanks Eric. BUT!!! It really does highlight the real gap in the learning/explanation gap between those who understand and those who want to!

For example, in the shader drop downs there are 4 main EnhanceC headings, each with individual dropdowns!.

I suggest that a majority of us dont know -not a clue-the whys and wherefores of usage/relationships of these groups.

(Some similar difficulties relate to the Terrain Tools brilliant plugin where it is really impossible to do things if anything is set other than strictly as per the tute--unable to work out variations which should be comon/normal acceptable variations?) 

It's not a critisism--it's spelling out that most of us are nerds needing spoon feeding!
