thats because one texture light can be as many as 7 -8 different lights
(up to 16 if -extra is turned on (3point oversampling) )
Lighting is a MASSIVE subject, and because of this, maybe there should be 3 tutorials on light?
the firt beeng very basic - no messing with command line switches etc..
the second : introducing light_environments, light_spot and a few basic params. for hlrad
and finally a complex tut covering lightflags - more advanced command line switches like ambient light in shade etc..
(i'm in way over my head)
