Excellent quality model of a Dodge Viper. No textures were used except for the tires, which are unwrapped. The rest of the model is not.
Geometry is quads with a few rare triangles. The model has 66,999 faces and 66915 vertices before subdivision. Renders were done with a subdivision level of 3. Subsurface level 2 was used for viewport pictures.
Renders were done with 2500 samples. A plane with an emission shader was used to light the interior.
With the exception of the tire materials, which were done in gimp, all work was in blender. The tires are also the only portion of the moodel that use textures, the rest is all cycles materials.
The interior is not highly detailed as this wasn't meant for interior renders. It is just there so there isn't a gaping hole that can be seen through the windshields.
