Light radius

[Soul-Blade]

I need the effect mode, and color settings to remove light from a light effect. Don't get this confused with light effects, which add light in order to make a lamp light effect...this is using a light effect to cancel out the light create with set effect, creating a normal light area within the radius (I made that way to complicated x-x)

Take a look at the screen to visually see what I need to do (image edited in PSP)
