3 questions:
Will it work on sa-mp?
Other people wont see it, right?
Do you bleed all the time or is it timer? can you stop it?
If the questions are "yes" then see the logic of this... making a movie with blood on sa-mp... ur friends(actors) cant see it but you can... simple go on teh place and press B to show blood, then walk away and say to ur actor to stand where the blood is and make him do a dead anim... just like SP blood
