How to turn a +30 weapon into a camo?

I remember reading somewhere that +30 weapons can be turned into weapon camos. I have the weapon at +30..now unsure how to change it to camo @_@

You need a Weapon Transmutation Pass which you can buy from the SG Shop; it technically doesn't turn it into a camo, but rather it changes the model of one weapon into another. Also, both weapons need to be at +35, not +30.

ahh thanks!
