@eXcess007 // Hmm... it has been a while since I looked at this grass tute..... Your problem may be because you have the hair properties set to 'mental ray primitive' which will not work so well with scanline. Also, lighting systems are simplified when using scanline for hair/fur/grass. Check your lighting too.
