There's another way you can do it. take a regular old primitve "Cone" and stretch it an place it where you need it. then go into the materials editor and click the inverted triangle that gives you your shaders,(uppermost triangle in the editor) you'll see "normal","blend transparency","fuzzy", and "Light". select "Light" and play around with the transparency and coloring and stuff.This way gives you the effect you want but isolates it to that particular area of the scene and you wont be waiting till new years day for the renderto complete. so essentially it's an object and you have all the control over it as you would with any other object. Hope this helps Hawwkfyr
