Qrad3 uses the game's textures to compute the color of light reflected & emitted by surfaces. ArghRad will display a table of these rgb color values when run with the -v (verbose) command-line option. The reflectivity (ref) value is the raw average color of all pixels in the texture (on a 0-1 scale). The emitted (emit) value is the lighting color if the texture casts light. This value can be very useful for matching a texture's color in the various color settings.

ArghRad can process a number of different texture formats. The following formats are supported (in order of search priority): .TGA (32 & 24-bit), .JPG, .M32, .M8, .PCX, and .WAL.

ArghRad needs to know the location of the base data directory to find the textures (and pics/colormap.pcx for Quake2). It tries to locate these directories automatically from the map's full filepath. There are options to specify these if it cannot find them itself.

ArghRad has the ability to read textures (and colormap) directly from inside the pak files. It first looks for unpacked files under the mod directory (if available), then reverse-alphabetically in any mod paks (if available), then for unpacked textures under the base directory, then finally reverse-alphabetically in the game paks. To take full advantage of this feature, you'll need a map-editor and qbsp3 that can also read textures directly from paks.

	-game  gamename	location: command-line    version: 2.50
	gamename: quake2, heretic2, kingpin (or: q2, h2, kp)	default: quake2
	Specifies which game the map is for: Quake2, Heretic2, or KingPin. Currently, only Heretic2 has a feature that requires proper game detection (SURF_TALL_WALL). Use this option if ArghRad doesn't automatically detect it.

	-gamedir  dirname	location: command-line    version: 1.00
	dirname: full file path to base dir	default: automatically set if possible
	Specifies the location of the base game data directory: baseq2 for Quake2, base for Heretic2, main for KingPin. Use this option if ArghRad does not automatically detect it, or if you are using a non-standard setup.
	no example image	no example map

	-moddir  dirname	location: command-line    version: 1.00
	dirname: full file path to mod dir	default: none
	Specifies the location of an optional mod data directory (ctf, rogue, xatrix, etc.). The moddir is needed if you are compiling for a game mod and using additional textures from that mod. Use this option if ArghRad doesn't automatically detect it.
