Hey All,

Excelent Tute Jim!!!!...Thats perfect!!!...I like your electronics analogy..I too am an electronics tech (No rocket science, just cameras), it gives me another way to look at the function editor...

 I too press the preview for confort, your right it makes you feel like you have done something..hehehe.

I just wanted to add something if I could... To get another perspective on the function editor, I recommend adding different preset materials to an object, and opening the function editor for that material to just have a look at how they were made...Heaps of things going on, it might give you ideas.

Thanks for the tutes Jim..Keep 'em coming.

Ivan.
