3D modelers are needed for creation of the cars. If interested, please go to THIS link, fill out the form, and make sure to mention you saw this on the Polycount forums. After that, I'll send you an email with what you have to do to be a part of the modding group (make an Assetto Corsa Forum account, etc.) and ask you what car you want to model.
