How to implement the generation of traces of blood on creatures?

Question

Unity

How to implement the appearance of traces of blood on "creatures" (players, animals, etc.), as their HP decreases? To make it clearer, I can give an example: in the game ARK (not advertising), when a dinosaur becomes very low in HP, these same traces appear. Question: how can I generate these traces (because I don't really want to draw a separate model with traces of blood for each "creature" in the game)?

Here is a similar article for UE, the basic principles are described there. I myself am not in the subject, I just threw off what I googled
