Hey Schmerzmittel(PainKiller),

I'm not a pro, but maybe I can help you.
You need the normal texture of your object and the specbump texture of your object.
You can create the SpecBump texture with a few programs like Photoshop with the nvidia plug-in.
After that you add thistextures to your model and link it to the script.
