Along with the image is a file which defines where the characters are. In the case of fonts, there is a .dat file which maps char->coordinates. In the case of model skins, this is a process known as "UV mapping", and the models contain the UV coordinates for each vertex.jkoder wrote:How is the game able to read an image like this? I've seen the same technique used for
weapon model graphics. Does it map to the unique shape of the character?

In which case the newer font support that TA added wont be much use to him.I do?o'dium wrote: He wants to replace the simple font seen in the console
