After being unable to find beard mods for Johnny up to my quality standards (over the years I've become a graphics whore when it came to texture quality), I decided to make my own. I took the beard from the IV Multiplayer model, and with some position & scale changing, and fixing the weight painting being applied on the wrong bones, successfully applied it on the Player version of Johnny K (the ped version didn't require any changes in regards to weights/bones).
