well, I did not say read the manual and memorize it. I agree it is not a newbie tutorial manual; it should be thought of as a reference manual, which means that when one is learning a new skill such as lighting, to find the section on lights and you can save yourself a lot of frustration. Everything you need to know about adding a light, deleting a light, changing the color and intensity are given, clearly, on two or three pages. No math! Good luck. ::::: Opera :::::
