LIGHTS (PlayStation lump)


View of the colors available for lighting.

The LIGHTS lump in the PlayStation version of Doom is a table of 256 32-bit binary little endian color values, stored in RGBA order. Each sector in the PlayStation port's map format contains a single byte field which serves as an index into this table to determine what special lighting, if any, that sector should have. Lighting of the contents of a sector with a non-zero light index is accomplished by modulating the selected RGB color with the ordinary PLAYPAL.
