This is the degree to which the highlights are sampled |

A value of one means that all highlights will be fully sampled |

using distributed ray tracing. |

A value greater than one causes multiple ray samples to be sent |

A value of zero means that no jittering will take place, and all |
| 346 |
|
reflections will appear sharp even when they should be diffuse. |

This may be desirable when used in combination with image sampling |
