Occasionally, when I have shaders on, one or so of the blood particles on the ground will not dissipate like it should, and will instead slide endlessly across the ground, creating a long streak of blood.
It looks weird.

Also, it eventually comes to a point where it makes weird markings wen they get far enough.

instead of it being a little mark it gets huge.

^hard to explain

but this was in friction.tbm so.. i'm not sure..

@playerID666

Do you mean something like this?

Yup.

Hmm, I've only had a problem like that when friction is off, but I'm sure this isn't related...
