The first modifier will also be used to shade the area leaving the |

|
antimatter volume and entering the regular volume. |

If mod1 is void, the antimatter volume is completely invisible. |

Antimatter does not work properly with the material type "trans", |

and multiple antimatter surfaces should be disjoint. |

If shading is desired at antimatter surfaces, it is important |

that the related volumes are closed with outward-facing normals. |

Antimatter surfaces should not intersect with other antimatter boundaries, |

and it is unwise to use the same modifier in nested antimatter volumes. |

The viewpoint must be outside all volumes concerned for a correct |
| 969 |
|
rendering. |
