Yes, decals. Again that sounds so very easy when you say it Onix. I have used decals for blood and I find it pretty hard to keep them in the correct place for several consecutive images with different poses. Also they do not wrap around a body because they work like an image projected on to a body. And how do you produce the normal images for the blood decals in a reasonable amount of time?
