   accounting for directional lights in a static lightmapp
  i wonder if anyone try to do this? or there is no purpose in implemneting it?anyway i was wondering how u all determine whether the lumel is facing the directional light...?thx!edwinz 
  A lumel has a normal right? A normal dot product between the lumel normal and light normal will do it, just there''s no attenuation. You can even handle shadowing by creating a ray from the lumel that travels a large distance in the opposite direction of the lightsource. This is useful for approximating sunlight or moonlight.
