Lighting - Radius
e Radius of a light is how far out from the center it will shine. Keep in mind that the size of your wearable lights has no bearing on the actual radius of the light itself. e images below
will give you an idea of how much space is lit with a few dierent radii. Remember—this is the radius; the sphere itself will be double the radius in diameter: a .25 sphere is .5 meters in
diameter—the size of a newly-rezzed prim. If the Fallo is set to 0 (see the next section), light will be cast from the center of the light ball right up to the edge, with a very quick fallo af-
ter that. In the real world, the photons will keep moving until they’re absorbed or reected. In SL, the light keeps going only until it hits the radius limit. erefore, if you want to light just
your model’s face, keep the radius small and the light close to the face. If you want to light up the room (and everybody in it), make the radius large; you can set it up to 20 meters!
