Back in the old day it was easy.

But.

I am using one of the textures from  "2009 chevy Camaro" by dreamlandmodels.

on a model but I want to add some lettering to the side,

so I applied the texture and OMG what the hell where/ how do I add lettering

I don't understand what half of that stuff is for.

HELP

any one have any idea how I can do it?

the model is UV mapped if that helps.

as always thanks ahead of time
