blood decal help

does anyone know where the alien/zombie blood decals are (the green ones) cause i hate the valve ones and want to change them. one more, how do you change the color of the blood that spurts out of enimies not the decals thanks.

C:\Program Files\Steam\steamapps\mreatyou\garrysmod\garrysmod\materials\decals\alienflesh I think.

don’t have that folder but it might be in half life 2 gcf. ill check.

“source materials.gcf”

i think thats for when the enemy gets shot not the blood that goes on the floor
