*ILLUMINATEFLAGS_NONE* |
None. |

*ILLUMINATEFLAGS_SHADOW* |
Full shadow calculations. |

*ILLUMINATEFLAGS_NOENVIRONMENT* |
Shadow calculations are enabled but no environment shading will be calculated. |

*ILLUMINATEFLAGS_DISABLESHADOWMAP_CORRECTION* |
Shadow maps evaluate the normal at a surface point, to avoid the problem of self-shadowing (that is otherwise inherent due to the way the algorithm works).
If a free point is sampled in space (where no surface is) this correction has to be disabled though, otherwise wrong results will be returned. |

*ILLUMINATEFLAGS_DISABLESHADOWCASTERMP_CORRECTION* |
Private. |

*ILLUMINATEFLAGS_LIGHTDIRNORMALS* |
Private. |

*ILLUMINATEFLAGS_NODISTANCEFALLOFF* |
Do not take distance falloff into account. |

*ILLUMINATEFLAGS_NOGRAIN* |
Do not take grain into account. |

*ILLUMINATEFLAGS_BACKLIGHT* |
Take backlight into account. |
