Custom Paint

Hi, A Friend and I are having a bit of a problem as we are working on a car and would like custom decals on the sides… I’d like to use the paint tool too spray it on, but I can’t figure out a way to make a custom image.

I’ve tried to replace “noughtsncrosses” in the materials/Decals folder, but I still get the same image as the original, I’ve tried adding a new file, with a different file name, but that doesn’t show up either…

I need a little help, thx^^

What software do you use?

I use CS4 with VTF extension…

Sorry for bumping this, but I really could use some help on this
