Achieving a blood design on white wall
Although I could see many blood splatter tutorials. I couldn’t see any tutorials on this specific topic.
I have this white clothed wall:

I want a different blood splatter effect to stick on the wall in subsequent fashion after each character has entered.
I have the fake blood and want to do the designs myself on other white walls then paste them in, like an overlay.
The more actors that come in, the more blood designs are on the wall.How do I achieve the blood on the walls from filming seperate blood designs? (or is there a better way?)
How do I deal with actors walking infront of the wall where I want the design to be?As you can see from the picture i’ve had a real, on set, physical trial already, but unfortunately with the actors coming in at different times the effect doesn’t stay as saturated for very long.

You would film each actor with his/her corresponding wall. Then, in a program like After Effects, you would want to draw a mask around the back of each walkoing character to introduce the new wall.
Just masking and more masking. This task doesn’t sound too difficult though. Just takes some time.

How I would approach this is all greenscreen. Walk your characters past a green or blue wall or curtain. Composite-in the final white wall, then you can make each blood splash its own layer and have precise control over all aspects of scale and position, etc. There are some very nice clips of paint “throws” and splatters for sale from digital juice in their compositor’s tool kit; you can grab any piece of that and colorize it to look like blood. This way, there’s no mess to clean up:-)
