Ok im playing with a ball inside a box trying to make an effect but it keeps giving me trouble i am pretty sure it has to do with the reflectivity of the surfaces. The effect i am trying to create is a highly reflective sphere (it has almost max reflectivity and max hardness and specularity) so it has a point of light on it in the center. Behind the ball i have a wall where i want a halo of light around the wall with its greatest intensity in the center and decreasing outward.
If anyone has done this before please let me know. Im just trying to make a cool light effect.
