Well I had a great idea for the pyro's IC, add the nose-art from an A-10 to distinguish it from the RPG... and after hours and hours of fooling around with tons of programs supposedly useable to create source models couldnt edit the model at all.
So I converted the RPG texture, and photoshopped it how I liked it... but it replaces the IC and the RPG because they use the same texture.
If someone could figure out how to make the IC model look to a different location for it's texture that would be sweet, but for now if you want this it will show up for both.
Download the following and place them in your fortressforever/materials/models/weapons/rpg folder. Back up your originals just in case.
