Hello - (TC6)

Blender's Autosmooth option (where you set an angle) is just for rendering and doesn't actually change the model normals. The edgesplit modifier can be set to a mode where it auto-smooths based on the angle, however, and that *does* change the model normals... although it's better to define your sharp edges manually. Basically, what you see in the 3D view mode in blender is what the normals are set to.

VDrift uses per-vertex normals from the model file (and the model file gets its normals per-vertex from blender). The per-vertex normals can be any direction (whatever blender sets them to). So, VDrift supports whatever mix of smoothness or solidness or sharp edges you define in blender.

Anyway, your model looks great -- we just gotta get it smooth in all of the right places. :-)
