2. In the Attribute Manager, choose the Caustics button; the Caustics area is displayed. In
this area, select the Surface Caustics check box and set the parameters as follows:
Energy: 8 Photons: 60000
The caustics are used to display the realistic patterns of focused lights in an image. The
Surface Caustics check box is used to add surface caustics in the scene.
The Energy spinner is used to control the brightness of the caustic effect by calculating the
total start energy of the photons. The Photons spinner is used to determine the number
of photons emitted from a light source in a scene. The number of photons directly affect
the intensity of the caustic effect.

window is displayed. In this window, choose the Effect button; a flyout is displayed.
