Scania STAX - concept truck 2002 - Download

(1/3) > >>

newS:
I've made this truck for Euro Truck Simulator, German Truck Simulator and Euro Truck Simulator 2 and now for Outerra:
see also here: http://www.trucksimsforum.de/viewtopic.php?f=235&t=15328

This is a high poly model (163.991 triangles)

I've finished a first version:

I am going to steal those rear tires off that truck and put them on the Jeep Wrangler.. My dream.

Bartolomeus:
Yes, the wheels are awesome! Great work on the Truck.

ZeosPantera:
Looks good. A bit more texture and it will be great. I think outerra can handle a bit more detail than EuroTruck simulator. If you don't mind I spent some time with the physics. Tell me what you think.
