i have coded a application that converts tga files to tex for nascar heat... this one is abit more advanced then others... when you select your image it displays in the app so you know you are converting the right skin!!!!
it checks that the skin is uncompressed aswell...
as long as you have your tga named... IE: carXXX.tga (XXX being your race number) after this has converted it.. it will remove the skin from the desgin view... but then you can click Write drivers ... it will pop up with a box... type in the chassis name and it will create the drivers.txt info for you! you also have the option to save the drivers.txt
hope you all like it
PS: you must install and run this as administrator!
