Exactly what the title says. Throwing knives currently have outlines but you can only see the outline if you have line of sight, making it impossible to see if the knife gets stuck under a body - this mod swaps the outline index for one that is the same colour but is also visible through walls (ala Payday 2).
I left the distance the same as default, so you can only see the outline if you are within 10m of the throwing knife - I can remove this and make the distance infinite if anyone wants, but I think 10m is probably enough.
