Floor Blood Splatter?

I have made a model of the inside of a house in blender for a level of my game, but I want to add a blood splat texture to the floor without having to change the floors texture? Would I make a 2D shape of a blood splatter and add the texture to that or is there some easier way? by the way I have also textured it in blender.

You just have to make a 2D plane/very slim cube inside Unity, then add a blood splatter texture to it and set the texture to RGBA, so it’s transparent.
