Thanks again, It's sods law that I have had the PLE Book Suite for a couple of months now, though the one book of the series that is on back order is the Texturing/Rendering book, lol. I'll chase up my order, if I'm still struggling to get my head around it I'll look into the book you suggested.

Though, admittedly I am terrible at self learning etc, I find it much easier to be shown something in person, as it appears to stick first time as opposed from trying to translate what others percieve as being stright forward tutorials which to me most of the time is simple jibberish!
