Description Sets the number of random directions from a source with a "Random directions into a sphere" ray directions type. Depending on the number of rays traced, it may be necessary to dimension ray index and ray counter variables as data type Huge_ instead of Long. Please see Multi-threaded Raytracing for more information.
