No, I want to know how they made the actual image, I know where to place it. I was wondering if there was a program that makes them.
Oh! Ok!
Well what I do for mine is this.
I took and exported the longest existing character name texture. Longest not in letters, but in pixel size.
I then went into photoshop and opened that file.
Use the paint brush. Make a layer on top of the texture that you paint completely black.
Then you make a text layer on top of that with the font you want.
Up to there is where I stop and save it as a template.
You can then type whatever name you want into the text, and then save as the png of it. Just don't ever re-save the original template with your edited name.
In some cases you may need to transform the text in order for it to fit.
That's basically it. (Maybe I should write a tutorial for this...)
