It took about three weeks to create. This is the first time I have modeled a vehicle so it was a great learning experience.
Modeled in Maya. Textured in Substance Painter.
Based on a 1942 Willy's Jeep.
Approximately 90000 tris without tires. One tire is 8000 tris. In these images each of the tires is a separate model and textured individually.
I did that to make each tire unique. In game they could just be duplicated for performance.
