Example: The Search Distance Parameter (Progressive)
For this example,
...
the
...
light used in the scene is
...
V-Ray Sun. The Caustics Mode is set to Progressive. The V-Ray Sun has its Photon emission properties adjusted as so: Caustics Subdivs are set to 1500; the Caustics Multiplier is set to 2 and the Photon Radius is set to 30 cm.

Example: The Search Distance Parameter (Photon Map)
For this image, the light' ss Caustics Multiplier parameterparameter (||Light|| > Advanced properties rollout > Caustics Multiplier) is set to 80 and the rest of the parameters are at their default values. AsAs seen from the images, the larger Search distanceDistance produces blurrier caustics.
