I made my James Bond BloodWall by adapting a Snow emitter. I can't remember what it was called originally (as I renamed it unfortunately), but essentially it was one of the generic snow emitters (not one with the 'snow flakes', just white dots). I then made them fall very slowly and made them very big. Then turned on the 'Don't Erase' option. And changed the colour. It wasn't perfect, but looked good.
Thanks! Do you still have the emitter? I would like to see it, because as you said if it's just OK it would not be acceptable. I just do not want to spent time to create it myself and get it rejected. If you don't it's OK too. I appreciate your help.
ONe day I will have to take the tutorial and learn about the program. Its wonderful software,
