BitMix

i don't have the iso anymore so, i will start with quickbms. open the program, a window will appear and you have to choose the bms script (select the BMS script to use) find the zip.bms its in the same folder. then select the zip with the car (example: AUD_RS6_03.zip) then select the folder, in which you want to extract. done. open forza studio (its in obj/debug folder) then File, Open, select the file, which name contains lod0 and it extension is carbin and the car is loaded, you will see the 3d presentation on the right. right click on the name on the right and select export. then you will have obj file. open it in 3ds max or some other program and export it in 3ds format. then you can import it in zmodeler. i should say, don't try further, because the modding in tdu is very hard, i can't explain everything, its much harder than to export simple file. i haven't made screenshots, because there is nothing to show. just follow the steps. Good luck!
