@procyonlotor hey i tryed it out but i still am not getting what i want (i do get half already correctly)
first i put in the collor ramp but it didnt worked well so i inversed the color flags and with the first blood splat it worked . but then the second isnt doing the same . these are the 2 setups i tryed

the left bloodsplat is good but right one isnt visible . now if i switch the other collor flag too like that then this happens 
hope someone knows what i do wrong
