How spawning blood by butchering recipe works?

[WolfgangPolska]

Hello, I wanted to make recipes in my mod to leave filth, after they had been worked on, in similar fashion how butchering table leaves filth(blood) when animals are buthered. yet I havent found any class, or def, or xml tag near in table and recipe defs to give that functionality. Does any know how it works?

Look in Corpse's ButcherProducts.

You can probably trace around from there to figure it all out.

FWIW, there's probably more than one way to do it - I would have expected it from the butchering toil, I suppose?
