Summary: I created these two material using substance designer. I designed the material "murder scene in the snow" And then I tweaked some settings and created another materiak "muddy snow". The two materials are all made up by three simple mateirlals: the footprint, the snow and the muddy puddle/the blood puddle.
Software: Substance designer, marmoset tootlbag 3

The result of footprint is not very promising before, but I managed to soften the edges a bit.
