Jason uploaded my translated version of the German H&D2 model tutorial I published 3 years ago. It is indeed just an excerpt of the complete tutorial and concentrates on some advanced techniques e.g. making new vehicle models without overwriting original cars and using the hex editor in order to change models and scene.4ds (the landscape of a map).
Hope this might be helpful for players who want to give modding a try
Many thanks to Jason
