DO/LIT

From Dark Omen Wiki

The LIT file seems to contain information about the lighting of the map. A quick attempt at breaking this file down follows:

struct Header
{
    int version;  (=1)
    int numberOfLightsInFile;
}

struct Light
{
    signed int X, Y, Z;
    int unknown1, unknown2;
    int color1, color2, color3;
}
