These global lighting settings are applied after all normal lighting has been calculated, right before it is saved to the bsp.
Note: The -nominlimit setting has been removed from ArghRad, and it is now the default behavior. The old behavior can be achieved by setting both -ambienta and -minlighta to the same value.

-ambienta brightness |
location: command-line version: 1.00 | ||
| brightness: 0-255 | default: 0 | ||
Sets the brightness of the ambient lighting. Ambient light is added to
every surface in the map, even where no other light is shining.
Brightness is a standard "absolute" level (easier than the original
qrad3's -ambient 0-2 scale). Note: This overrides any _ambient light settings in the Worldspawn. |

default: 0 default: 0 0 0 |
||
Sets the brightness of the ambient lighting from within the map's
Worldspawn. Ambient light is added to every surface in the map, even
where no other light shines. The value can take one of two forms:
brightness - A single brightness value for plain white ambient
light.
red green blue - Three separate brightness values for red, green, and blue ambient lighting (not a standard RGB color). |

-maxlighta brightness |
location: command-line version: 1.00 | ||
| brightness: 0-255 | default: 196 | ||
Sets the global maximum brightness level. All lighting samples
brighter than this value are scaled down to match it. This helps keep
the lighting from becoming too bright for the game to display properly.
Brightness is a standard "absolute" level (easier than the original
qrad3's -maxlight 0-2 scale).

-minlighta value |
location: command-line version: 3.00 | ||
| value: 0-255 | default: 0 | ||
Sets the global minimum brightness level. All lighting samples
darker than this value are scaled up to match it. Brightness is a
standard "absolute" level. Note: This setting's behavior has changed from previous versions of ArghRad (where it was just a synonym for -ambienta). |

|
||
-minlight value |
location: command-line version: 3.00 | ||
| value: 0-2 | default: 0 | ||
This is the same as -minlighta, except it uses
the original qrad3's 0-2 brightness scale (brightness = 128 * value).
Use of -minlighta is recommended instead.

-gamma scale |
location: command-line version: 3.00 | ||
| scale: 0-1 (darker), > 1 (lighter) | default: 1 | ||
Sets the gamma scale, used in applying a gamma correction curve to the
final map lighting. Values less than 1 will darken the lighting. Values
greater than 1 will brighten it.

-nocolor |
location: command-line version: 1.00 | ||
| no values | default: disabled (color on) | ||
Converts all colored lighting to plain white light. It uses a
color-weighted formula similar to a black-and-white TV:

|
|
||
-nocoloru |
location: command-line version: 1.00 | ||
| no values | default: disabled (color on) | ||
Converts all colored lighting to plain white light. The colors are
"unweighted", they all contribute equally in the conversion:

|
||
-saturation scale |
location: command-line version: 3.00 | ||
| scale: 0-1 | default: 1 | ||
Scales the saturation of the colored lighting. Scale ranges from 0.0 (no
color) to 1.0 (normal full color). Note: By default, this option makes use of the -nocolor formula. This can be changed to use the -nocoloru formula by also including -nocoloru on the command-line. |

-onlybounce |
location: command-line version: 2.00 | ||
| no values | default: disabled (all lighting saved) | ||
Ignores the normal lighting, and only saves the bounced light to the
bsp. Originally added just for testing purposes, but mappers may find it
helpful too.

For bsps that are already lit, ArghRad can update various aspects of the existing lighting without having to perform the full light-casting calculations.
|
|
||
-update |
location: command-line version: 3.00 | ||
| no values | default: disabled (normal lighting calculations) | ||
Skips the normal lighting calculations, and just updates the existing
lightmaps using the other global settings specified. Settings that can
be used with -update are:
-ambienta, -ambient,
-saturation, -nocolor,
-nocoloru, -scale, -gamma,
-minlighta, -minlight,
-maxlighta, and -maxlight. Note: Changes are generally not reversable, so it may be smart to backup the .bsp first (otherwise it will require a normal full relight). Also, using -update many times successively on the same .bsp may degrade the quality of the lighting. |
