Spot Point Light ControlsSpot Radius The radius of the circle sphere that emits light . If the spot light is seen as a cone, this is analogue to truncating the cone tip where the cone has a radius equal to Spot Radius. A very small value makes the cone near ideal. Increasing the Spot in all directions. Increasing the Radius will soften the lit region edge and the shadows casted by the spot light.
Visible to Camera Makes the light source visible to the camera (a.k.a primary rays). Drop Off Specifies the rate at which the light intensity decreases from the spot light beam center to the edge.Since the point light is rendered as a sphere with the specified Radius, the visible shape will be a sphere. Note that a Radius of 0 might still produce a very tiny visible dot. This option is only available in 3Delight for Katana.
