Setgamepalette

setgamepalette <pal_ID>

Switches between the palettes that Duke Nukem 3D uses. The palettes are located in LOOKUP.DAT. This command can take values between 0 and 6.

It sets the palette that the game uses to 0, the normal game palette. (Remember that these palettes include underwater palette, night vision palette etc. so this can be used to block them)
