Reflectors　Light Size

[sagarasousuke 10]

How should I do to change the size of a conic optical axis though I make the searchlight by using Reflectors?

It did not change though size was changed from 1.0 to 0.0.

  	class Reflectors
	{
		class main_reflector
		{

			color[] = {1.0, 1.0, 1.0, 1.0};
			ambient[] = {0.1, 0.1, 0.1, 1.0};
			position = "light";
			direction = "lightEnd";
			hitpoint = "light";
			selection = "light";
			size = 0.0;
			brightness = 5.0;
		};
	};
