Hi Supradevil,

The tracks are just deformed nurbs toruses (torii??? (what's the plural of torus???.

Grab the inner hull of the torus ring and scale it out. Then grab the control points at the edges of the shape and pull them in vertically (assuming you have the track the same way up as mine).

Then you've got the central control points. YOu'll find that these make the track shape a bit rounded so scale them in too.

Basically it's just a flattened torus as I say. Fiddle about with it and you'll get it.

Then I converted from nurbs to polys and smoothed them off.

The wheels are just poly cylinders.

As for making em realistic, I think that it's best to do bump mapping for the treads. Like I said in a previous post it will take time to add them to the model. I _think_ if you do them black and white the tracks will stand out.

I'll post my bump map on here (if it works!!) to show you what I've done. Then you can do something similar.

Hope this helps and you're vey welcome (any time!!).

Ask me if I you're stuck.
